CGS-240 Humidity Generator

Continuous, high-accuracy humidity generation

MSRP - $125,000

The CGS-240 is a fully automated two-pressure, two-temperature humidity generator. This portable, self-contained system produces stable atmospheres of known humidity and temperature to provide accurate humidity and temperature for the calibration of humidity sensors, hygrothermographs, chilled mirror hygrometers, and other environmental measuring devices.

G2 Dew Point Generator

Precise generation of humidity controlled gas flow

MSRP - $125,000

The G2 produces highly accurate humidity values, delivering a humidified gas stream, accurately controlled to a variety of user-selectable humidity parameters such as %RH, dew point, frost point, ppm, or vapor pressure. By accurately measuring the temperature and pressure at the point where the humidified gas is utilized, the G2 automatically adjusts for changes in dynamic conditions such as heat load or ambient pressure variation.

With RH Systems’ hybrid humidity generation technique, the G2 is a true humidity reference instrument suitable for high accuracy calibration, product conditioning, and test applications.

G9 Humidity Generator

Precise humidity generation

MSRP - $125,000

With the G9, produce highly accurate humidity values without relying on water vapor content measurement. Using the NIST-proven “two-pressure” humidity generation technique, this system will generate a variety of humidity values such as %RH, dew point, frost point, ppm, or vapor pressure. Additionally, the system is computer-controlled, allowing it to run at fixed points, or multi-point profiles, completely unattended.

G3 Frost Point Generator

Better accuracy and performance for low frost point humidity generation

MSRP - $125,000

The G3 is a low humidity generator that encapsulates essential tubing, pressure regulator, flow regulator, and saturator within a sealed vacuum chamber. This eliminates atmospheric water vapor permeation and the need for thermal insulation materials in and around thermally controlled components. Additionally, Free-Piston Stirling Coolers are used to cool the saturator.

An improvement over conventional designs, the G3 has better accuracy and performance at low humidity, improved thermal insulation and control, faster cool down characteristics, and better maintenance access.

373 Dew Point Mirror

High precision, fast response, customized configurations

MSRP - $125,000

High precision, fast response, customized configurations Body: RH Systems’ 373 Dew Point Mirror features a full-color, high-resolution LCD touch screen that displays data clearly, ensuring you get the information you need, when you need it. With intuitive configuration customizations, you can set up your screen exactly how you want it, and the system will remember, showing the same configuration every time you power it up. A front-mounted mirror provides quick and easy access for cleaning.

473 Dew Point Mirror

High Performance Chilled Mirror Hygrometer

MSRP - $125,000

Get highly precise, stable and repeatable results. Featuring MBW chilled mirrors used by national standards and accredited laboratories worldwide, RH Systems’ 473 Dew Point Mirror transfers reference standard performance into applications such as climatic chamber validation, relative humidity calibrators and a wide range of industrial processes. With an intuitive user interface, ForceFrost™ function, and automatic mirror check function, the 473 is easy to use with minimal maintenance.

973 Dew Point Mirror

Direct and accurate humidity measurement

MSRP - $125,000

RH Systems’ 973 Dew Point Mirror is portable, equipped with an integral measuring head for both spot and continuous measurement of dew/frost point and temperature in air and gas mixtures. The 973 ensures direct and accurate humidity measurement, ready for immediate use, complete with built-in pump, flow meter, pressure sensor, and external temperature probe.

973-SF6 Analyzer

Laboratory precision. Field ready.

MSRP - $125,000

The 973-SF6 Analyzer was specifically designed for measurement of humidity and SF6 purity in gas insulated switchgear systems. With its internal gas containment/recovery system, the 973-SF6 provides the best measurement solution available within a single instrument.

Unlike capacitive sensor-based systems that rapidly and continually drift far out of specification, the 973-SF6 chilled mirror technology relies on the drift-free physical principles of condensation. While sensor-based systems may have a lower initial acquisition cost, their ongoing costs for humidity sensor replacement, recalibration, and the lower reliability of their measurements, make the 973- SF6 the most cost effective option.

PT12 Precision Thermometer

High-precision, multi-channel thermometer system for validation and calibration

MSRP - $125,000

The PT12 is a highly precise and stable platinum resistance thermometer-based, multi-channel temperature measurement system. With a custom-designed, high-quality measurement circuit and full current reversal and multiplexed sampling, the PT12 provides 12 channels of low uncertainty temperature data for validation and calibration engineers.

Employing a full reversal current source, the PT12 eliminates polarity sensitive errors normally inherent to DC measuring techniques. Increased accuracy comes from referencing all measurements to high-stability, temperature-compensated internal reference resistors.

REVIEWS

“Bob is more interested in the subject matter and the science behind his products than in making a sale. He wants to make sure that a solution will work for us. Beyond their products, RH Systems will continue to innovate and amaze the humidity community with new systems and instruments that will advance the metrological community.”

Tee Yee Zheng Supertron Sensing

RH Systems helped me understand the systems better. That makes me ask better questions and ultimately become a better technologist. They show that their customers are clearly everything. From the way they treat us, you can tell that people must absolutely love working there.

Paul Gomez Sandia National Labs

“Bob and the staff at RH Systems are the greatest and their undying devotion to supporting the community is greatly appreciated. They are prepping the next generation of professionals in our community for a continuation of support unparalleled in temp and humidity and should be a beacon for all metrology.”

Joseph Rindone Metrologist at Paladin Metrology Advocates

“RH Systems goes the extra mile, without fail. And they stand behind what they do. Customer service is a dying art. RH Systems still gives you one-on-one attention and they always pick up the phone. In our industry, we have a lot of red tape. Bob helps us navigate this and wants to take on the challenge of forming a custom solution. He is invested in what his customers need. That speaks volumes.”

Roger Free Calibration Technician at Haleon

“RH Systems has created the best frost point generator in the world. The G3 is very fast, has high precision and is still very easy to use. The three separately flow-controlled outputs give you maximum flexibility when connecting measuring devices.”

Helmut Hager CEO, Techmetrics

“I’ve never met anyone who wants to do more than what his customers expect than Bob. I respect and admire that philosophy so much! You will never regret doing business with Bob Hardy!”
