Solinst 122 Interface Meter - Laser Marked

The Completely New Solinst 122 Interface Meter features a PVDF laser marked tape. Laser marking means the tape resists staining and is easier to decontaminate than other meters. The model 122 interface meter is a versatile tool for measuring product levels in wells, tanks and other environments.  Certified as intrinsically safe, the New Solinst interface meters can be used in potentially explosive locations when the included grounding strap is properly deployed. Featuring a high quality design that makes obtaining accurate readings simple. The New Solinst 122 interface meter comes with improved electronics and with the new laser marked PVDF tape it makes for a more durable design - the markings on the tape last longer and don't fade as quickly.

Features and Technical Specifications

• Accuracy: The 122's sensors are calibrated to the same zero point, allowing you to obtain readings accurate to 1/200th ft. See below for information about obtaining readings.
• Probe: A 5/8" OD factory-sealed probe features a stainless steel shield for long-term protection. The probe requires no calibration or other user maintenance.
• Battery: The Solinst 122 is powered by one standard 9V battery that can deliver up to 120 hours of on-time use. Battery is easy to access and swap out in the field if necessary
• Tape: Laser marked PVDF tape lengths to 1000 ft (300m).  Non-stretch, non-corrosive tape is available with either metric or imperial markings. Tape is easy to clean and handle and features a dog bone design that won't adhere to narrow well walls.  The PVDF tape can be used on models 101 and TLC meters.
• Safety: The 122 is certified intrinsically safe, certified by the Canadian Standards Association for use in Class 1, groups C and D hazardous locations and ATEX certified.
• Power saving: An automatic shut off after ten minutes prevents unnecessary battery use.
• Warranty: Solinst interface meters have a three year warranty. As an authorized Solinst dealer, Environmental Equipment & Supply handles all warranty issues directly.

Obtaining Product Measurements

Use the Solinst 122 interface meter to obtain accurate measurements of both light non-aqueous phase liquids (LNAPL) and dense non-aqueous phase liquids (DNAPL). The 122's infrared sensors trigger a steady light and tone when in contact with LNAPL or DNAPL product; when the sensors touch water, they produce an intermittent signal. Because of this, obtaining product measurements is easy.

LNAPL product floats on top of water; to detect and measure the presence of LNAPL, simply lower the 122's probe until the sensor is triggered. An intermittent light and tone indicates an absence of LNAPL. If a steady signal is produced, take a depth reading. Continue lowering the probe until the steady signal turns intermittent, and then take a second reading. Subtract the larger number from the smaller, and you will know how much LNAPL product is present.

To measure DNAPL, continue lowering the probe until the intermittent signal turns solid. Stop and take a reading, then continue to lower the unit until the bottom of the well is reached. Subtracting the depth the DNAPL layer started from the total depth of the well will give you an accurate measurement of the amount of product present.
