Extech RH600 Dew Point Meter

Extech RH600 Dew Point Meter

The Extech RH600 is a high-precision meter designed to accurately measure and log dew point levels in compressed air systems. This device is essential for manufacturing professionals to safeguard product quality and prevent damage to pneumatic equipment, corrosion, and issues in cylinder and valve systems. Equipped with a color graphical display, the RH600 delivers clear and stable readings, capable of measuring dew point temperatures as low as -50°C (-58°F) at a maximum ambient pressure of 20 bar.

Extech RH600 Key Features

Accurately measure dew point as low as -50°C (-58°F) at ambient pressures up to 20 bar.

Ensure reliable readings with the sensor purge/purification feature, allowing the probe sensor to dry quickly after exposure to moisture.

Insert the probe sensor directly into the compressed air system via a G1/2” thread.

Measure low humidity (RH <5%) with high accuracy (±0.025%).

Easily monitor dew point on the color graphical display with a user-friendly menu interface.

Log and transfer up to 32,000 data sets to a computer in CSV format using a USB cable.

Set high/low thresholds for temperature, relative humidity, and dew point with visual and audible alarms.

Includes RH601 Dew Point Probe, AC adapter, Micro USB to USB-A cable, 3.7 V Li-ion battery, and hard case.
