The Testo 175 H1 Data Logger for Temperature and Humidity Monitoring

Accurate, reliable monitoring for buildings and closed spaces

The testo 175 H1 data logger measures, monitors, and records temperature and relative humidity with high precision. It features an external humidity sensor (stub) for faster response times and a security lock to prevent tampering. In addition to temperature and humidity, it also logs dew point values. The clear display shows current readings, adjustable thresholds, breached limits, and remaining battery life.

Reliable performance and security

Equipped with advanced technology, the testo 175 H1 provides secure, dependable measurements. Its large memory stores up to 1 million readings, and long-lasting batteries offer up to 3 years of operation. This allows flexible data readouts even with short measuring cycles. User-replaceable triple AAA batteries are included in the delivery scope.

Programming and analyzing your data
