Testo 770-3 - TRMS Hook Clamp Meter (Voltage, Current, µA, Temperature Measurements, Bluetooth)

Description

The Testo 770-3 (0590 7703) is the most advanced model in the 770 series of TRMS hook-style clamp meters. It features a unique, fully retractable pincer arm for measuring cables in tight spaces and adds several functions beyond the other models, including Bluetooth connectivity and power measurement.

Key Features

• Unique retractable pincer arm: The innovative "grab mechanism" allows the pincer arm to be fully retracted into the instrument. This enables users to clamp onto tightly packed cables in crowded control cabinets, ensuring both safety and measurement accuracy.
• True RMS measurement: Provides precise and reliable readings, especially on distorted or irregular AC voltage and current waveforms found in modern electrical environments.
• Automatic detection: The meter automatically detects and selects the measurement mode for AC/DC current and voltage, simplifying operation and preventing incorrect settings.
• Bluetooth connectivity: This feature is a key difference from the other 770 models. It allows the meter to connect to the Testo Smart App on a smartphone or tablet (iOS 11.0/Android 6.0 or newer), enabling remote viewing, data logging, and the creation of custom reports.
• Power measurement: Measures active (W), reactive (kvar), and apparent (kVA) power, as well as power factor. This is useful for analyzing the performance of electrical systems.
• μA measurement range: Measures microampere (\(A\)) current, which is useful for testing flame rods and ionization current in HVAC systems.
• Temperature adapter: An included adapter allows the meter to be used with a Type K thermocouple probe (ordered separately) for temperature measurement.
• Inrush current measurement: Measures the starting current for electric motors and other equipment.
• Extended voltage range: The meter can measure AC/DC voltage up to 1000 V.
• Safety rating: It has an overvoltage category of CAT IV 600V and CAT III 1000V.
