0590 7701 770-1 TRMS Clamp Meter by Testo

The testo 770 Hook-clamp Digital Multimeter (DMM) is ideally suited for electrical work in HVAC applications. Testo's unique hooking clamp can be used to separate then grab wires. The easy hook-off retractable post releases the wires when testing is complete. You can safely work in tight spaces without using your hands. The 770 series identifies the testing in-process and automatically selects the correct meter configuration which saves you time and increases your accuracy.

The 770 series of instruments are rich in the features HVAC techs need and want including TRMS, starting current, and frequency measurement. The 770-2, which includes A can also measure temperature using the included Type K thermocouple adapter. The 770-3 (temperature adapter optional) additionally includes real-time power measurements (Watts), and Bluetooth. The 770-3 links to the Testo Smart Probes App and can be used for remote viewing, monitoring trending over time, and creating reports. The powerful app allows you to create custom reports that include photos, data, and graphs that can be saved or sent via email.

Testo's history of efficiency, innovation, and quality now extends into the entire electrical lineup. Once again, Testo brings high value, feature-packed products to the HVAC contractor market.

S350CDHF pH Sensor, Flat, Polymer, 12mm, HF by Sensorex

The specification sheet serves as an addendum to the pH LabSpecs sheet and covers all lab pH electrodes suitable for use in hydrofluoric acid.

Specifications differences for use in hydrofluoric acid (HF) are shown in SPECIFICATIONS section below. Please note 2 major differences as compared to standard electrodes. First, pH range is 0-12 not 0-14. Second, the temperature range is 0-50 deg C.

This series of electrodes are compatible with any lab or portable pH meter. Calibration of these electrodes is as normal with any standard pH electrode using standard pH buffer solutions.

• Resist attack and etching from HF (up to 2% v/v)
• Resist coating and fouling
• Compatible with any pH meter
