With over 40 years of experience in flow measurement and control, we are extremely well placed to assist in specifying and supplying instumentation for your application, from single instruments to bespoke automated systems. Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
Chell Instruments are the UK distributor for the 'SAES Pure Gas' range of gas purification equipment. These offer incredible purification performance over a huge range of gases and flow rates through the use of absorber, adsorber, catalyst, heated getter and palladium membrane purification technologies.
We also supply a range of gas handling solutions, from full, bespoke gas panels to high performance needle valves and regulators.
Chell offer a wide range of equipment for the measurement and control of gas pressure. This could be a very high-end primary pressure standard, benchtop calibrator, portable calibrator or simply a single transducer. We can also provide bespoke, automated pressure measurement systems tailored to your exact process requirements.
Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
Chell supply a range of temperature scanners to complement the pressure scanners
Chell Instruments offer a wide range of high quality and reliable vacuum measurement instrumentation for use in a huge variety of applications and industries.

Models 7250xi and 7250i offer advanced percent of reading precision for increased capability with a single instrument, reducing the investment required to calibrate a wide variety of pressure devices and ranges.
The Model 7250xi provides 0.005 % of reading precision from 5 % to 100 % of the instrument's range. This unmatched precision is achieved through unique quartz pressure sensing technology and multiple quartz sensors in a single instrument. Various ranges from 0 to 20 and 0 to 2 500 psi (0 to 140 kPa and 0 to 17.2 MPa) are available.
The Model 7250i provides 0.005 % of reading from 25 % to 100 % of range and is available in various ranges from 0 to 5 and 0 to 2,500 psi (0 to 35 kPa and 0 to 17.2 MPa).
For pressure below the lower threshold of 5% for the 7250xi and 25 % for the 7250i, the precision becomes 0.005 % of the lower value. For example, a 1,000 psi (7 MPa) Model 7250xi provides 0.005 % of reading from 50 to 1,000 psi (0.035 to 7 MPa); the precision for pressures from 0 to 50 psi (0 to 0.035 MPa) is 0.005 % of 50 psi (0.035 MPa).
Computer interface: Every Series 7250 is provided with both an RS-232 and IEEE-488 interface, and Series 7250 syntax follows SCPI protocol for easy programming. A LabVIEW® driver is available as a free download. As a standard feature, software written for the previous generation Series 7215, 7010 and 6000 instruments is fully supported by the Series 7250. The Series 7250 can also be set to 510 emulation mode to use software originally written for the DPI 510. Firmware updates can also be performed over the RS-232 interface (updates can be downloaded from the web site). The 7250 series is compatible with COMPASS software.
