Referring to the wireless technology, Bill Spohn, product manager, HVACR, for Testo, noted that the "accurate and easy-to-use" battery-powered probes can be used up to 65 feet away from the handheld Compact and CompactPro meter. "With this technology, you now can really be in two places at the same time," said Spohn.
A user-installed module (similar to a cell phone SIM card) adds wireless capability to the appropriate meter in each class, he said. Reliable, secure RF transmission technology provides the flexibility to place a probe anywhere it's needed, he said. In the end, this allows the technician to perform multiple tasks, complete long-term measurements, all without instrument cables, climbing ladders, or hanging from unsafe positions.
Testo's Compact series instruments have been redesigned with a sleek, ergonomic shape, larger backlit screen, and essential functions, all available from a four-button keypad.
