Ametek Calibration Instruments will be showing three new products for the first time in the UK at the Mtec show (14-15 February, 2007, NEC Birmingham, UK)
These new products are the Jofra ATC-125 ultra cooler - the world's first dry-block calibrator capable of reaching -90C, the compact Jofra DPC-500 high resolution documenting pressure calibrator, and the Jofra DTI050 handheld digital temperature indicator, which offers a measurement accuracy of +0.005C.
The new Jofra ATC-125 ultra cooler can reach -90C and also has a temperature range of 215C (-90 to 125C).
Featuring patent-applied for free piston stirring cooler (FPSC) technology for cooling, together with a special heating element, the ATC-125 offers high accuracy and excellent stability.
Most importantly, its extremely fast heating and cooling makes a five point calibration up to five times quicker than with an equivalent liquid bath.
It can be used equally as easily in a laboratory or factory environment.
The Jofra DPC-500 documenting pressure calibrator has set a new standard for pressure calibration.
Designed for high precision calibration of pressure instruments such as pressure gauges, transmitters, digital manometers, pressure switches and overpressure valves, the DPC-500 offers improved pressure accuracy (+/-0.025% FS), better electrical current (+/-1.6uA) and voltage (+/-0.5mV) accuracy and an extended pressure range of 250mbar to 1000bar FS.
The DPC-500 also offers absolute pressure measurement from 0.4 to 16 bar absolute.
The Jofra DTI050 handheld digital temperature indicator features a fast response time which ensures precise monitoring of temperature stability and low drift which reduces uncertainty of measurement between calibration intervals.
Supplied with a Jofra STS-050 'smart' temperature reference sensor, the unit becomes a fully traceable thermometer with excellent accuracy of measurement.
It can be used as the reference for accurate verification of temperature for both dry block and liquid bath temperature calibrators or for direct measurement of critical temperatures in a process environment.
