With over two decades of gas detection experience, NOV M/D Totco’s Wellsite Gas Watch™ wireless portable gas monitor takes reliability to the next level. NOV M/D Totco’s proprietary infrared technology provides a real time analysis of Methane (C1), Propane (C3), and Total Gas with reliable, repeatable accuracy. The system allows for easy hook- ups to any Electronic Drilling Recorder that utilizes Wellsite Information Transfer Standard protocols. Secure wireless communication from sensor to work area removes personnel from exposure to H2S or high Lower Explosive Limit levels of combustible hydrocarbon gases.

We Value Your Safety
The Wireless Wellsite Gas Watch Dual Sensor Gas Monitor is explosion proof and CSA/UL Class I, Division 2, Group C and D certified for both Canada and United States. The tough aluminum enclosure ensures that the wireless gas monitor will withstand the harsh environments of drilling rig operations.

+Lag Adjust
• Allows the user to graphically adjust incorrectly calculated data on the depth log and automatically recalculates the desired annular velocity.
+Auto Lag
• Once set, monitors the pump rate and alters the lag calculations based on percent pump rate changes.
+Auto email Logged Ascii Standard Files and PDF Logs
• When connected to a satellite network, a Logged Ascii Standard file or PDF log for any depth or time interval can be automatically sent to any requested email address.
Printed Logs
• Print time based or depth based logs using 1:240 or 1:600 scales.
