Technical Specifications

Measurement Functions

Temperature Measurement

The testo 608-H1 uses an NTC temperature sensor and measures temperatures from 0 to +50 °C, with an accuracy of ±0.5 °C at +25 °C and a resolution of 0.1 °C. 

Relative Humidity Measurement

The capacitive humidity sensor measures relative humidity from 10 to 95 %RH. It provides a resolution of 0.1 %RH and an accuracy of ±3 %RH across the specified humidity range. The sensor is designed for long-term stability. 

Dew Point

The instrument calculates and displays the dew point, making it useful when monitoring environmental conditions where condensation and moisture levels are important. 

Min/Max Values

The device can display the minimum and maximum temperature and humidity values, allowing users to review changes in environmental conditions without requiring separate data-logging software. 

Applications

The testo 608-H1 can be used for monitoring environmental conditions in:

• Laboratories

• Offices

• Warehouses

• Storage areas

• Garden centres

• Living spaces

• Indoor climate monitoring

• General environmental monitoring

• Temperature- and humidity-sensitive areas

It is particularly suited to applications where users need continuous visual monitoring rather than electronic data logging or measurement-data management. 

Display & Operation

The large two-line LCD provides clear visibility of the measured environmental parameters. The instrument is designed for straightforward operation and continuous monitoring, making it suitable for users who need readily accessible temperature, humidity and dew-point information.

Installation & Mounting

The testo 608-H1 can be used in two ways:

Tabletop placement:
Position the instrument on a desk, shelf, workbench or other flat surface.

Wall mounting:
The integrated mounting arrangement allows the instrument to be positioned on a wall for convenient continuous monitoring. 

Power Supply

The instrument operates using a 9 V block battery (6F22). Battery life is approximately one year under typical conditions. The display provides an indication when the battery is approaching the end of its service life.
