Sniffer Leak Detectors: GasCheck Handheld Sniffer Leak Detectors Description A handheld, portable, battery operated leak detector for sniffing helium and other gases using thermal conductivity technology. Principally calibrated for helium, the unit has multiple gas selection. Fitted with a large back lit LCD, the display shows unit setting and numerical readout, even in dark, confined spaces. When searching for leaks the unit can easily be set into auto-range, giving the maximum sensitivity when required. Peak hold control allows accurate reading of leak rate, which is useful where external or traceable standards apply. The GasCheck uses a robust micro thermal conductivity sensor to detect any gas providing it is different from air. It is calibrated for Helium but works well with Ammonia, Argon, Butane, Hydrogen, SF6 and some refrigerants. The newly-released LHHLD-G3 (GasCheck G3) is an upgrade to the LHHLD-3000 (GasCheck 3000). The new G3 features the following upgrades: Readings in ppm, cc/sec, or mg/m^3 Data logging of 10 points New graphical icon display menu Rapidly detects almost any known gas or gas mixture. Particularly sensitive to helium and hydrogen. Calibrated by customer or at factory Try Before You Buy If you want see how the GasCheck will perform on your application before you buy, you may "try and buy" a new GasCheck G3 for $225 for a one week period. LACO will then credit you up to $200 towards the purchase price of this detector if you decide to purchase with a credit card by the end of the weeks rental. Otherwise, you may return the leak detector and pay only the "try and buy" fee.
