Digital Teslameter 152 (NEW)

Digital Teslameter unit, touchscreen interface, serial communications, for temperature compensated and non compensated probes.

Features

  • Because the probe characterisation information is stored in the probe assembly itself, any Group3 probe can be used with any Group3 DTM. However for full accuracy the DTM-152 should be used with a probe that has temperature compensation circuitry.
  • Digital filtering (time averaging) can be enabled to suppress short term fluctuations.
  • Two analog outputs are available. These are a buffered version of the raw probe signal, and are not corrected for linearity or temperature.
  • Panel mount versions are available, and panels with correct cut-outs and mounting hardware.

Quick Facts

  • High accuracy - fully temperature compensated
  • Resolution of 1 part in 600,000
  • 4 ranges
  • Maximum field 3 Tesla
  • 7" Touch Screen
  • Ethernet and RS232. GPIB Available soon.
  • Accuracy is 0.01% of reading + 0.006% of full scale when used with MPT-141 probe
  • Temperature range for instrument and probe 0 to 50° C

The following specifications refer to DTM-152 with LPT-141 probe (standard size probe).

DTM-152 with MPT-141 probe (miniature probe)

Four ranges, selectable from front panel:

0.3
0.6
1.2
3.0 tesla full scale

Note: Resolution depends on the range selected, and whether the digital filtering is enabled.

Note: Resolution available at the serial⁄GPIB port is greater than that of the display.
