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.
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.
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.
FEATURES
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.
Key Features
