(1) Self calibration: The sensor probe can automatically calibrate the zero point, eliminate system errors caused by zero point and drift, ensure the accuracy of each measurement, and avoid the tedious annual calibration.
(2) Fast gas saving: After starting up and entering the measurement state, the measurement time for SF6 gas dew point is about 2 minutes.
(3) Self locking joint: using German imported self-locking joints, safe and reliable, without air leakage.
(4) Data storage: Designed with a large capacity, it can store up to 200 sets of test data.
(5) Curve function: The large screen curve displays the dew point measurement process.
(6) Clear display: The color LCD screen directly displays dew point, micro water (ppm), ambient temperature, ambient humidity, time, and date.
(7) RS232 interface: can be connected to a PC serial port for data transmission.
(8) Built in power supply: Equipped with a 4Ah rechargeable lithium battery, it can work continuously for 10 hours on a single charge.
