• No calibration or other maintenance required
• Wide assortment of tubes available to detect over 300 gases and vapors
• Springless piston design accurately draws 50 and 100 cc volumes
• Compatible with LP-1200 piston hand pump, a reliable way to draw samples of an exact volume required for the most accurate measurements
• Tight vacuum seal is formed by a greased plunger gasket
• Tapered rubber inlet accommodates a range of tube diameters for different types of tubes
• Inlet filter prevents glass pieces and dust from entering the shaft
• End-of-flow indicator in the handle turns white when the gas sampling is complete
• Pump stroke counter is rotated to keep track of the number of strokes completed
• Using the standard number of pump strokes, the concentration of the gas is read from stain length directly matched to the printed scale after the listed sampling time has elapsed
