Formed in 1976, Chell Instruments' objective has always been to provide measurement & control instruments & systems appropriate for our customers' needs. From original sale, through design & manufacture to performance testing and calibration, a skilled engineer is in control. Most of our engineers began their careers with us whilst in college or university and remain loyal employees with unparalleled expertise in their fields. Many of our products carry firmware and are run in conjunction with a computer running software written by our specialist engineers for use by our customer's engineers and colleagues. This results in very practical solutions to often very complex measurement and control problems. Every measurement instrument delivered is offered with calibration in our UKAS accredited ISO17025 laboratory so that our customers may be assured that the performance of their new device has the lowest possible uncertainties.
