Humidity Calibrators and Handheld Hygrometers


	S-503 Humidity Calibrator The S-503 Humidity Calibrator is a light-weight and portable, affordable instrument that can quickly and accurately generate a stable humidity setpoint. This makes it ideal for checking, validating and calibrating RH sensors, transmitters and data loggers in critical applications. Special Features: Extremely portable, (only 1.85 kg with desiccant and saturation chambers integrated) Generates humidity levels between 10 and 90% RH in 0.1% intervals Fast stabilization of chamber humidity (0.5% RH in just 10 minutes) Accuracy of ±2% RH, traceable to international standards Up to 7 sensors can be calibrated simultaneously (Diameter 5 to 24mm) Digital display of calibrator can show 4-20mA signals, 5V signals and 10V signals Power output provided on calibrator for supply to connected probes Independent RH reference meter (optional) Data sheet S-503 RH calibrator


	S-904 Humidity and Temperature Generator The S-904 Humidity and Temperature Generator is the ideal instrument for calibration and verification of relative humidity sensors and transmitters. With a chamber temperature range of 10 to 50°C, a to date unparalleled temperature uniformity across the chamber room and the ability to generate 10-90 % RH, performing accurate and repeatable calibrations is made easy and effective. Special Features: Relative humidity and temperature control chamber Excellent stability within chamber (±0.2 %RH, ±0.05°C) Optional in-built data-logging for reference probe and probes under calibration Probes with body diameters between 5 to 25 mm can be accepted Accuracy of ±1% RH, traceable to international standards Temperature generation from 10 to 50°C, with ± 0.1°C stability Data sheet S-904 Humidity and Temperature Generator


	Opti-Cal - Humidity Calibrator with integrated, traceable chilled mirror reference The Opti-Cal is a stand-alone calibrator for RH sensors providing humidity and temperature profiling with a built in, traceable cooled mirror reference hygrometer. Special Features: Easily perform RH sensor calibrations in-house Easy to use, fully self-contained system Digital control of chamber temperature and humidity values Calibration range 10 to 90 %RH over 10 to 50°C chamber temperatures Integrated traceable reference hygrometer Best measurement capability <2 % of reading Data sheet Opti-Cal humidity Calibrator
