The PC-4 sample dryer condenses water vapor from an airstream, drying the airstream to a dewpoint of 1 degree C (user-settable between 1 and 5 C). This reduces the water vapor pressure in the airstream to no more than 0.66 kPa (at 1 C), at which point the dilution effect of water vapor in the air sample is negligible in many applications. Specifications:Accuracy and Resolution: Accuracy 0.25 C, resolution 0.01 C Analog Output: 0-5 C = 0-5V output with 16 bit resolution Condensate removal: Miniature diaphragm pump, user-settable actuation from 1/minute to 1/30 minutes, actuation duration user-settable from 1 sec to 30 sec Flow Rate: 25 ml/minute to 5 liters/minute Internal A/D Conversion: 16 bits Operating Temperature: 5 - 35 degrees C, relative humidity non-condensing. Panel Display: Digital 2-line alphanumeric LCD, simultaneous display of set and read temperature Power Requirements:12 VDC at 8A. Universal (90-240 VAC) external power supply included. Range: 1-5 degrees C, in 1 C increments Regulation: PID (Proportional Integral Derivative), deviation < 0.05 C RMS Serial Data Output: Comma delimited ASCII string of all measured parameters, resolution 0.01 C, standard RS-232 serial, polled or auto-sent at user definable intervals from 0.5 - 600 seconds.
