Multiple High Resistance Standard - MHS
- 1 MEGOHM TO 1 TERAOHM
- FULLY GUARDED
- HIGH IMMUNITY FROM AMBIENT TEMPERATURE CHANGES
Ohm-Labs' new Multiple High Resistance Standard maintains state-of-the-art resistance at levels above 1 megohm.
The MHS incorporates seven fully guarded high resistance standards, identical to those used in Ohm-Labs' 100-H series resistance standards.
The 1 and 10 megohm elements are wound from resistance wire for high stability. The rest are custom made to Ohm-Labs' specifications using precious metal oxide as the resistance element.
Every resistor is housed in a hermetically sealed housing for immunity from humidity and pressure effects.
A constant temperature chamber provides isolation from variations in ambient temperature. A precision thermometer indicates chamber temperature. A thermistor and two wells are provided for an external monitoring.
The chamber may be set from 18 to 30 °C to characterize temperature coefficients. The MHS temperature stabilizes in less than an hour, allowing high resistance standards to be used in the field or on-site with the highest accuracy.
ISO 17025 accredited, NIST traceable calibration is included.
For less than the cost of seven high resistance standards, the model MHS provides superior performance and greater versatility.
