DOPO2 All-in-1 Handheld Optical Gas and Dissolved Oxygen Sensor,High Performance

Description

Dissolved oxygen sensor with an embedded EOM (Electro Optic Module) and embedded temperature and pressure sensors for monitoring of oxygen in both gaseous and aqueous environments. The outer diameter of its stainless-steel probe is 5/8" (15.875 mm) and it is 10" (25.4 cm) long.
This fluorescence quenching based fiber optics sensor is hydrocarbon compatible and can be used to monitor dissolved oxygen in Organic solvents, Alcohols, fuels, oils,…. The sensor patch (HCR series) held in place by a screw-on cap with a response time less than 1 Sec. The sensor cap can be replaced with another cap or a fiber optic probe.
The DOPO2 connects to a PC via USB connection and can be configured with single-channel LED excitation and detection, and modulation frequencies up to 31.2 kHz. The on-board pressure transducer and thermistor measure atmospheric pressure and sample temperature.
Temperature data is used for sensor temperature compensation
. Sensor cap is rated up to 55 bar pressures.
DOPO2 Viewer Software and standard factory calibration is included.
