Model 1200 Mini “Two-Pressure” Humidity Generator

Product catalog summary

Overview
The Thunder Scientific Model 1200 Mini "Two-Pressure" Humidity Generator is a precision instrument designed to produce accurate humidity values using the NIST-proven "two-pressure" principle. It is suitable for instrument calibration, environmental testing, and generating multipoint humidity profiles.

Features

Automated humidity generation with computer control.
Real-time data display, storage, and printing.
Touch-screen control with USB and Ethernet interfaces.
Compact design occupying only 4 square feet of floor space.

Principle of Operation
The system generates humidity by saturating air or nitrogen with water vapor at a known temperature and pressure. The process is controlled by a computer system that manages temperature, pressure, and mass flow using PID algorithms.

Specifications

Relative Humidity Range: 10 to 95% with 0.5% uncertainty.
Dew Point Temperature Range: -20 to 50 °C with 0.1 °C accuracy.
Chamber Temperature Range: 10 to 60 °C with ±0.04 °C stability.
Saturation Pressure Range: Ambient to 152 psiA.
Gas Type: Air or Nitrogen with a flow rate of 2 to 10 L/min.

Applications

Calibration of chilled mirror hygrometers and humidity sensors.
Environmental testing for various materials and products.

Test Chamber
The test chamber is made of stainless steel and measures 6” x 6” x 6”. It includes an access port for probes and sample tubes.

Utilities

Electrical Power: 100/240 V, 50/60 Hz.
Gas Supply: 155-175 psiG at 0.5 cfm.

Embedded 1200 ControLog® run screen. Temperature Control: Ultra stable temperatures are attained through solid-state thermoelectric cooling and heating of a circulating fluid that jackets the test chamber and associated humidity generation components. Chamber and saturation temperatures are governed by this medium which is computer controlled at any value between 10 °C and 60 °C using PID (proportional-integral-derivative) algorithms. Pressure And Flow Control: Pressure control and mass flow control are accomplished through computer actuation of electromechanical valve assemblies. Saturation...
