The DPP: surveillance kit includes DX/C meter with 3 electrodes. The electrode E12 is mainly used to measure wood, wood floors and subfloors, even without removing the floor planks. The slim shape and long pins of the electrode E14-m allow for measuring in corners, under baseboards, around window sills, behind wall cavities, places which cannot be reached with the integral pins of a meter. The electrode E16 is for measuring hard building materials such as concrete, brick, tile or grout that other electrodes cannot easily measure.
The package DPP-M consists of:
- mini-Ligno DX/C moisture meter
- Electrode E12 with 1 pair each DA and DZ pins
- Electrode E14-m with cable and 1 pair EG pins
- Electrode E16 with 1 pair EC pins
- mini-BNC cable for E12
- mini-E16 cable for E16
- Case M
mini-Ligno DX/C: The moisture meter of your choice, the mini-Ligno DX/C is the most advanced among the mini-Lignos. It comes with pins and a connector built-in for external electrodes or monitor cables. Features are the wide measuring range and 46 correction settings built-in for measuring domestic and tropical wood species, making this meter a good choice when you accurately want to measure wood floors. In addition gypsum and different types of wall boards, bamboo and panel products. and a reference scale for building materials such as concrete are also included.
For wood: The integral pins at the mini-Ligno measure 7/16” deep. When measuring thicker lumber, you can make a fresh cut and measure the end grain to reach the core. If it is not feasible to cut the wood, you can use the electrode E12 for depth measurements.
For building materials: The pins on the meter work well in soft materials such as drywall for a depth of 7/16″. If corners and tight places cannot be reached with the integral meter pins, use the electrode E14-m or E16, whichever is more convenient. Add EL pins for measuring in-depth up to 7″ deep.
Electrode E12: The E12 is designed to measure from the surface to 2″ deep (with DB pins). All E12 pins are insulated and measure only at the tip. The slide hammer helps inserting and removing the pins. As pins are hammered into the material, consecutive readings show the moisture distribution within the material at every depth level the pins are driven to. The ability to measure a moisture gradient is one of the main reasons for our customers to use the electrode E12.
Wood: Taking numerous readings as pins are inserted, indicate if a moisture gradient exists or if the wood is dry throughout the core. Making sure wood is evenly dried is the best assurance for quality wood products. The thicker the wood, the more important core readings become. When inspecting wood floors, using the E12 gives you a tool to assess moisture distribution through floor planks into the sub floor without having to remove any floor planks. Using the electrode E12 with insulated pins guarantees measuring accuracy at a defined depth from surface to core.
Restoration: The moisture in structural components even behind wall coverings can be checked with the electrode E12. When assessing water damage, the pins of the E12 can be driven to different depth levels and thus indicate how far water has been absorbed or if there is still residual moisture inside the structure after drying. Insulated pins can measure dry material behind wet surfaces.
E12 pins are teflon-coated to only measure at the tip. This is important to determine if a moisture gradient exists from a dry surface towards to wet core, but it is equally important to be able to measure through a wet surface to determine how far moisture has been absorbed and at what depth the material stayed dry.
The electrode E12 comes with 1 pair each of 1″ pins and 1 pair of 1.5″. The 2″ long pins need to be ordered separately.
E12 pins are teflon coated to only measure at the tip and come in three sizes:
– DZ Pins insulated, measuring depth 1”
– DA Pins insulated, measuring depth 1.5”
– DB Pins insulated, measuring depth 2” (order separately)
Electrode E14-m with EG pins can be used for measuring moisture on any surface up to 3/4″ deep with insulated pins EG. In addition, the slim shape of the E14 allows checking tight places, around pipes, below window sills, in wall corners, places which cannot be reached easily with other hand probes. If the pins are hammered into the material, consecutive readings show moisture changes within the material at every depth level the pins are driven to. Adding the 7″ long EL pins lets you reach through insulation or under baseboards into structural components. Great for EIFS inspections.
The knob at the end of the handle can be removed and replaced by a paint brush handle or broom stick. Using the paint brush handle allows to extend the reach to keep a safe distance from mold infested areas and still be able to get reliable measurements. Extending the handle with a broom stick makes measuring carpets and carpet padding easy without crouching down. Ceilings can be checked for moisture leakage without a ladder.
Pins measure only at the tip. EG and EL pins are teflon-coated up to the electrode handle. Moisture from a wet surface is never picked up, even if the pins are pushed all the way into the material.
Using the external electrode E14-m allows you to keep the meter display visible in front of you. Measuring ceilings, walls or floors with the meter itself can make it impossible to read the numbers on the display.
Electrode and pins are very sturdy and allow hard pounding to insert pins into hard materials. Works for strand bamboo as well as hard and cementitious panel products.
Electrode E14-m comes with a cable with a slit end and 2mm plugs to fit the mini-Ligno C’s,
and 1 pair EG pins.
EG pins teflon coated, measuring depth 3/4″
EL pins teflon coated, measuring depth 7″
Electrode E16 is used mainly to measure hard building materials, such as concrete slabs, brick walls, tile. The electrode can also be used when the distance or the angle between the 2 measuring pins need to be changed. Standard distance between pins is 1 1/4″.
The electrode E16 consists of two separate posts. Each post is 2″ long with a ball head. The cable is connected through a hole in the post using a 4mm banana plug. The bottom of the posts have threads for the pins. An assortment of pins is available with lengths from 3/16″ to 7″ (Pins EG, EL and EC, EA, EV). Tapping on top of the ball head with a mallet or hammer will drive pins into the material. Pre-drilling holes maybe required for deeper measurements.
We recommend a distance of 4″ (10cm) between the pins for measuring cementitious materials including concrete. Cementitious materials have a very low electrical resistance compared to wood and tend to give high values, therefore changing the distance allows a wider moisture range.
Measurements obtained from concrete or cementitious materials are not true percent values. They only can be used as reference numbers or comparative readings. Comparative measurements become meaningful, when a dry (wet) sample piece of the material is available. Measurements can then be compared to the moisture value for dry (wet).
Using the mini-Ligno DX/C with the Electrode E16 gives immediate results when measuring concrete. The measurements can show areas of high and low moisture. If measurements are taken with the EL pins at different depth levels, the moisture profile of the slab becomes obvious. However, it cannot replace the in-situ probe test or the Calcium-Chloride test which allow to determine, if a wood floor can be installed.
EC pins are included in package DPP-M
