February 28, 2013 – Milwaukee Electric Tool has introduced the 2270-20 contact temp meter, featuring a dual thermocouple input and delta T calculation to help users better identify and address temperature issues in heating and cooling systems, it says. The contact temp meter measures from 1372C to -200C (2,500F to -325F), and using the data collected, the meter will also calculate the Delta T of the two temperatures. A timer function also allows users to track minimum, maximum and average temperatures for up to a 24-hour period. The meter boasts a simplified keypad and interface, and a high-contrast white on black display to make reading the display easier from far away and in all lighting conditions. Additionally, a magnet and strap allows the meter to hang during use for hands free measurement.
