Its very cold at -200 degrees and the team at Sentry has been working on our new Watchman -200, The Watchman system is a WifI based sensor that as standard covers -55 to +85 degrees, with a demand for monitoring going beyond these temperatures we have developed the new watchman -200.
This has been perfect for Vaccine fridges going down to -80 degrees, the sensor can take reports every 5, 15, 30 or 60 minutes.
Although we don’t have clients using it down to -200 we did some testing with the aid of one of our clients who tested it in liquid Nitrogen and the reading was -197.2 which is where they expected it to be.
