5 decades box, PT100 box simulator
  This highly-accurate 5-decades resistance box is designed to simulate a Pt100 platinum probe. It proves itself particularly useful for the adjustment and verification of the PID regulators or converters for the Pt100 probes/output 4 – 20mA ..
£19.95
6 decades resistance box
  This 6-decades box (10 x 1mΩ to 10 x 100Ω) is used for simulating a platinium probe and calibrating the Pt100 converters. The resistors are wound with aged manganin and the switches are airtight. ..

Differentials probes
  These probes are used for displaying and measuring of dangerous voltages with a Class I oscilloscope, in accordance with the user safety standards. In fact, the image voltage applied to the oscilloscope is no more than a few volts. On the other hand, by using two probes the voltages applied to the oscilloscope inputs are isolated from one another. So, differential probes can measure high voltages (DP50) and/or voltag..

Measuring Amplifier : Measurement Amplifier (115 V, 50/60 Hz)
Measuring amplifier for recording very small voltage, current and charge. For display purposes, any DC meter capable of measuring in the range up to 10 V can be used with no additional configuration. Including offset correction and polarity switch. Additional outputs are provided so that the -15 V and +15 V operating voltage can be tapped for use in external circuitry, e.g. bridge circuits. Input: BNC sockets Measuring range with referen..

Measuring Amplifier : Measurement Amplifier (230 V, 50/60 Hz)
For the measurement of extremely small currents, voltages and charges in electrostatics and atomic physics. A voltage signal proportional to the measurement variable is available and can be supplied to a voltmeter as a display instrument. Over voltage protection up to 300 V provided by a high-voltage-proof input. Includes a built-in fixed voltage output for external circuit connections (e.g. measurement bridges). Measurement ranges (with respe..

Measuring Amplifier : Measuring Amplifier S
For the measurement of extremely small DC and AC voltages and currents. A voltage signal proportional to the measurement variable is available at the analogue output and can be supplied to a voltmeter to be used for display. The measurement amplifier is equipped with an operational amplifier and a special pre-amplifier, which provides for a high gain factor, a low offset voltage and long-term stabilisation. Measurement ranges (with respect t..

True RMS DC & AC low current probes
  These probes are used with an oscilloscope, a multimeter or a recording instrument. They deliver a secondary image voltage of the primary current (a few dozen millivolts), thereby allowing the user to take measurements in complete safety and without having to switch off the power to the circuit. The Hall sensor fitted in them can detect a DC component overlaid onto the AC component. When used with a true RMS multimeter, these pr..
