Testo 770-3 Hook-Clamp Power Meter with Bluetooth/App Review

By Max | 10:23 AM MST, Thu April 20, 2017

The Testo 770-3 Hook-Clamp Power Meter is a very unique hook style clamp meter that has many different features that help separate it from the traditional clamp meters you usually see on the market. The Testo 770-3’s most prominent characteristic is how exactly its hook retracts. The problem with traditional clamp meters is the hook opens outwards making it harder to use in tight spaces and increases the difficulty of grabbing onto wires.

Testo 760-1/760-2/760-3 Digital Multimeters with New Auto Range Detection Technology Reviews

By Sam | 11:35 AM MST, Tue October 04, 2016

     Hello, this week we will be discussing two new offerings from Testo. The first is the Testo 760 Digital Multimeter and the second will be the Testo 770 Hook-Clamp Digital Multimeter. Electrical test meters are a new market for Testo but it makes sense why they have decided to enter it; to meet the specific needs of the HVAC technicians who are using their other products.

Testo 330-1G LL - Review - This Combustion Analyzer has more features for more jobs

By Max | 10:15 AM MST, Tue September 29, 2015

Testo 330-1G LL is no longer manufactured.

Today I am reviewing the 330-1G LL Combustion Analyzer with Color Graphics from Testo. The Testo 330-1G LL is designed to measure O2, CO, (NOx option), draft & temperature (ambient & flue) in addition to calculations of CO2, efficiency, excess air, and CO air free. This can be exceptionally useful for emissions monitoring, maintenance and tuning of combustion processes such as burners, boilers, diesel and gas engines, laboratory analysis, heaters, kilns, furnaces, turbines, water heaters, and more.

The Testo 870-2 is no longer in production.

The “hot” (pun intended) new section of the thermal imaging marketplace is point-and-shoot entry-level cameras, and manufacturers are eager to offer cameras that have an excellent intersection of price and features. The new Testo 870-2 offers just this – high end features within a reasonable budget.
