Chell Instruments offer a wide range of high quality and reliable mass flow meters, controllers and systems suitable for use in a wide range of applications and industries.
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.

The Chell FlightDaq 2 is a development of our previous FlightDaq model. The FlightDaq2 is smaller than its predecessor and has more features including absolute/differential measurement, IENA protocol, smart power supply and low power consumption heaters.
Internally, the FlightDaq2 builds on the proven Micro-Daq / MicroCAT architecture to provide up to 2KHz per channel data acquisition. This is combined with the pneumatics necessary to give full control of the scanner functions including re-zero and purge.
The enclosure features an inner machined case which is heated and insulated from the external case. This, combined with a micro-processor controlled heater array gives a highly stable operating tempera-ture and low overall power consumption.
The FlightDaq2 uses a pressure scanner which pro-vides full thermal compensation with an accuracy of 0.05% of full scale (after re-zero and depending on range - see accuracy table). The output of the scanner is differential which, combined with the internal shuttle valve control, enables any zero offset to be removed.
This differential measurement is combined with a precision barometric sensor to enable the user to select between differential or absolute outputs.
The FlightDaq2 features a smart sensing power supply that will shut down the unit if the supply rails moves outside its operating band. When the power rail returns to normal, the FlightDaq2 will restart and resume operation.
External connectors are the Chell SQDC (32 channel) or the Chell AQDC-HD range (64 channel). The SQDC option enables either flexible or solid tubing to be used for the measurement lines. The supply gas and purge connectors are via Swagelok or Chell AS series quick disconnects.
The flightDaq2 is designed for on-engine as well as airframe applications and as such is tested to the D0160G vibration and shock standards.
The FlightDaq will output high speed engineering unit data over Ethernet (TCP/IP or UDP), CAN or IENA.
For ease of setup, the FlightDaq is fully configurable using an embedded web-server .
