Amprobe TMD-10 Handheld Dual Temperature Digital Thermometer

We run a HVAC company and have a bunch of these in service. They have been great, no failures to date. These units have an adjustable offset that is digital and stored in memory. Before switching to the TMD-10's, we used a competitor's product that used a potentiometer to adjust offset. It was difficult to set and would change over time. The TMD-10's keep their adjustment even through daily commercial use!
