Building on the strengths of the long and popular lineage of its Aquatemp predecessors, the new Therma 20 Plus is tougher, has ten times the battery life, additional Min/Max & Hold measurements, a backlit display and still retains the IP66/67 water and dust resistance rating.

The Therma 20 Plus was designed to be submerged or washed under a running tap, so it's ideal for food processing applications where cleaning is paramount.

Its large clear display includes probe status and Min/Max/Hold information, so you know exactly what you're reading but most importantly, the (temperature value) numbers are 15mm high – nice and easy to read!

Offering even more versatility, the Therma 20 Plus's probe is replaceable, so the one instrument can be used in a broad range of applications. Talk to Metermaster about probe options.
