It can also be used to check the drying condition of wood. 【Features】 ■ 7 types of material properties (2 types of wood, 5 types of building materials) ■ Relative humidity, wet bulb temperature, dew point (606-2) ■ Hold function ■ Self-test function *For more details, please download the PDF or feel free to contact us.

The Testo 616 wood and building material moisture meter measures the moisture content of wood and building materials by passing high frequency through and detecting changes in capacitance. It can also be used to check the drying condition of wood. Additionally, it measures moisture at depths of up to 5 cm, making it useful for confirming leaks after diagnostics with thermal imaging and other methods. 【Features】 ■ 10 types of material characteristics (3 types of wood, 7 types of building materials) ■ Measurement at a depth of 5 cm ■ Hold function ■ Maximum and minimum value display *For more details, please download the PDF or feel free to contact us.

The "testo 552BT" is a digital vacuum gauge that employs a Pirani-type sensor. It is suitable for vacuum pumping during the installation of refrigeration and air conditioning systems and heat pumps. It calculates the evaporation temperature of water (TH2O), the ambient temperature (Tamb), and the temperature difference (Δt). Additionally, we also offer the refrigerant detector "testo 316-3/316-4," which is necessary for the maintenance of refrigeration and air conditioning equipment. 【Features and Functions】 ■ Smartphone-compatible digital vacuum gauge ■ Long-life sensor that requires no maintenance ■ Calculates the evaporation temperature of water (TH2O), the ambient temperature (Tamb), and the temperature difference (Δt) ■ Display with backlight ■ Threshold setting available ■ Auto power-off function *For more details, please download the PDF or feel free to contact us.

The "testo 760" is a digital multimeter that can be easily operated with buttons instead of a rotary switch. It automatically recognizes whether the test leads are connected for voltage or current, eliminating the need for switching operations. It features automatic switching between AC and DC ranges. Additionally, it can measure μA for frame rod inspections (760-2/-3). 【Features and Functions】 ■ Button operation ■ Automatic switching between AC/DC ■ Average value response type (760-1), true RMS type (760-2/-3) ■ Resistance, capacitance, frequency, continuity test, diode measurement ■ μA measurement capability for frame rod inspections (760-2/-3) *For more details, please download the PDF or feel free to contact us.

The "testo 770" is a true RMS AC/DC clamp meter with a vertical opening and closing jaw. It can easily clamp in tight spaces with its vertically opening sliding jaw, and it can measure inrush current during motor startup as a true RMS value. Additionally, we also offer the fork tester "testo 755," which allows you to test voltage, current, phase rotation, resistance, and continuity without button operation. 【Features and Functions】 ■ AC/DC automatic switching ■ True RMS ■ Inrush current measurement ■ μA measurement (770-2/-3), power measurement (770-3) ■ Maximum, minimum, and average value display ■ Hold function ■ Bluetooth communication (770-3) *For more details, please download the PDF or feel free to contact us.

The "testo 745" is a non-contact voltage tester that allows for two levels of sensitivity switching. It features an IP67 waterproof and dustproof design, and it notifies you with an LED light and sound when it detects electricity. It can switch sensitivity between two ranges: 12–1,000V or 50–1,000V. Additionally, we also offer the "testo 750" voltage tester, which is user-friendly with button operation and can automatically recognize voltage and current measurements. 【Features and Functions】 ■ Supports voltages up to 1,000V AC ■ IP67 waterproof and dustproof design ■ Two levels of sensitivity switching: 12–1,000V or 50–1,000V ■ Notifies with light and sound when electricity is detected ■ Equipped with an LED light *For more details, please download the PDF or feel free to contact us.

The Testo 540 is a pocket-sized compact device that quickly and easily measures illumination levels in offices, workspaces, and stores. 【Features】 ■ Quickly and easily measures illumination levels in work environments ■ Spectral sensitivity characteristics equivalent to the human eye ■ Hold function, maximum/minimum value display ■ Comes with a protective cap for safe storage *For more details, please download the PDF or feel free to contact us.

Testo 545 is a light meter designed to measure brightness in office and work environments, compatible with general LED lighting. It can quickly calculate time averages and multiple point averages, and with mobile app integration, you can use features for second screens and recording/documentation. Being corded allows the light sensor to be placed in areas without the shadow of the measurer for accurate measurements. 【Features】 ■ Backlight ■ Hold function ■ Maximum/Minimum values ■ Average (time/multiple points) ■ Damping ■ Auto-off ■ Sound alarm ■ Printer (optional) ■ Mobile app integration *For more details, please download the PDF or feel free to contact us.

This illuminance meter has spectral sensitivity characteristics equivalent to that of the human eye, capable of covering a wide range from dark environments to outdoor daylight (up to 100,000 lx) without the need to switch ranges. 【Features】 ■ Clearly structured operation menu and color display ■ Compliant with DIN EN 13032-1 and DIN5032-7 Class C ■ Measurement data can be saved in CSV format in the built-in memory and exported to a PC via USB ■ By adding other probes and accessories, it can support multi-item measurements with a single unit *For more details, please download the PDF or feel free to contact us.

Testo 535 is a handheld CO₂ meter that accurately measures indoor carbon dioxide concentrations. It uses an NDIR sensor with excellent long-term stability. With mobile app integration, logging for several minutes to several hours is also possible. 【Features】 ■ Backlight ■ Hold function ■ Maximum/Minimum ■ Average (time/multiple points) ■ Damping ■ Auto-off ■ Sound alarm ■ Printer (optional) ■ Mobile app integration *For more details, please download the PDF or feel free to contact us.
