PW series of intelligent temp and pressure digital instruments are the products of our company. We are the initial designers and vendors of the double-function digital instruments. PW series consist of PW300, PW300dual, PW600, PW800 and PW900. They incorporate the advantages of the same products from foreign countries in 1990s, as well as new features are added. Actually, they are quite suitable for measurement and control at one point for temp and pressure. PW series are good-looking and of excellent EMC performance.

New features:

• Two-layer digital LEDs with four-bit for each layer display actual pressure value and temp value;
• Pressure and temp alarms can be easily set;
• The output can be generated by relay, voltage pulse or silicon via constant voltage or constant current;
• System operation is controlled by the key panel;
• Calibration can be easily completed just by pressing CAL key on the key panel.

Three new technical methods are introduced to enhance the EMC performance:

• Photoelectric modules insulate the microprocessor from input and output interface;
• New anti-jamming methods are used in the system program;
• A hardware monitor runs all the time, which can reset the system to normal operation from abnormal operation after distortion.
• Easy operation
• Enter manual mode after system start;
• Press ‘Switch’ key to directly configure the set pressure value;
• Press ‘+’ key to increase output power;
• Automatic switch between manual and automatic mode;
• A row of LEDs to display output power;
• Output voltage can be litmited.
