HS-2 closed reel
The HS-2 line of Oil/Water Interface Sensors use tough, plastic reels to protect the stainless steel tape from damage and dirt while the tape is stored on the reel. They are made from black polyethylene and their lightweight and slim profile make them very portable.

Add to quote
More info

The polyethylene coated 3/8" stainless steel flat tape is available in both metric and imperial graduations. (Metric tapes are graduated to the nearest millimetre; imperial tapes are graduated to the nearest 1/100 of a foot.) The tape is manufactured with a probe connector at one end and a circuit board connector at the other. This allows the tape or the probe to be quickly and easily replaced should either become damaged.

The sensor's probe is 5/8" diameter and is constructed from 316 stainless steel. The probe is snapped into the side of the reel in a probe holder when not in use. This probe contains the ultrasonic transducer that is used to detect the presence of hydrocarbons and the conductivity sensor that detects water.

The HS-2 Closed Reel is only available with either a 30 meter or a 100 foot tape.

Water Level meter
  • Measure product thickness layers of 1/400 ft or ½ mm (sheen). Measure LNAPLs (floating) and DNAPLs (sinking) product.
  • Adjustable water sensitivity for extremely quick detection of water through very viscous oils. Get a reading in SECONDS versus 2-3 minutes!
  • Accurate Kynar tapes with spring steel core maintains accuracy of .008%- less then .001 inches stretch with a 35 lbs load

  • Damage proof optics- works regardless of severe damage or scratches. No need for expensive probe replacements or spares.
  • UNIQUE probe tip protects water sensing pins and optical sensor when shroud is removed
  • Exclusive 7/16" Interface Probe- the ONLY cost effective way to monitor Direct Push wells (unit pays for itself on the very first well!)
  • Protect your investment with our light-weight aluminum "Rugged Reel". No more broken plastic reels!
  • Field-tested Viton strain relief with 3-stage 2000 PSI pressure proof internally sealed probe- no weak link to leak or fail or cause the probe to hang at an angle which can give false positives for product
  • Ergonomic frame with excellent ground clearance for winding or use the "third hand" casing hanger to hang unit on the well casing while you take readings
  • All tapes comply with or exceed the US GGG-T-106E or EEC CLASS ll standards.
  • All tapes have numerical markings every foot, and 10th of a foot with bar graduations every 100th of a foot. (Available with metric scale in meters, cm and mm).
  • Units available from 50 feet up to 2000 feet or metric equivalent.
  • Four times more accurate than flat white TV cable type tapes that use twisted or spiral conductors which allow ½ inch of stretch/100 ft from the cables own weight.
  • Kynar covering is about 4-5 times harder( Rockwell Hardness) than softer polyethylene white tapes which are far more easily cut and damaged and require frequent repairs. White tapes will become softer when exposed to gasoline and other solvents.


Interface meter
Interface meter

The oil/water interface meter is used to accurately measure the thickness of floating product (LNAPL) above the water table. It will also detect and measure sinking layers of DNAPL. This interface meter with its slim probe 5/8in (13mm), is ideal for wells, piezometers and direct push equipment as narrow as 3/4in (19mm) ID. The probe and tape will withstand hydrocarbons, solvents and other contaminants. This unit is used by professionals involved with the monitoring and remediation of groundwater contaminated by oil products. The oil/water interface meter is suitable for wells, boreholes, underground and above ground storage tanks.

The rugged PID 2000 is the smallest pumped handheld volatile organic compound (VOC) monitor on the market. Its Photoionization Detector’s (PID) extended range of 0-10,000 ppm makes it an ideal instrument for applications from environmental site surveying to HazMat/Homeland Security.

The PID 2000 detector can be made wireless with the use of PIDLink2. This allows real-time monitoring information from the detector to be integrated into an existing AreaPID system. A wireless, RF (radio frequency) modem allows detectors equipped with Firmware version 1.20 or higher to communicate and transmit readings and other information on a real-time basis with a remotely located AreaRPID base controller up to two miles away.
