PORTABLE DC MAGNETIC FIELD MEASUREMENT
The TES10B is a handheld digital Gauss/Tesla meter for measuring DC magnetic field and flux density. It offers a wide measuring range, simple operation and a clear display, with hold functions for measure value and peak value, switchable mT or Gs display units, and zero reset by key. Its compact body and backlit 4.5-digit LCD support convenient checks of permanent magnets and other magnetic materials in laboratory, production and field settings.
1. Wide measuring range — covers DC magnetic fields from 0–200 mT to 0–2,000 mT, with 0–2,000 Gs to 0–20,000 Gs
2. Switchable units — readings can be changed over between mT and Gs
3. Hold functions — holds the measured value and the peak value for later reading
4. High resolution — 0.01 mT and 0.1 mT resolution, with 0.1 Gs and 1 Gs
5. Clear 4.5-digit display — 4½ LCD gives an easy-to-read value at a glance
6. Zero reset by key — resets the zero point directly from the keypad
7. Flexible power — operates on a 6 V DC adapter or 4 × AA batteries
The instrument is supplied with a measurement probe and a power adapter in a carrying case, and the battery compartment takes four AA cells for cordless operation.

1. Reset zero before measuring — use the zero reset key with the probe away from the magnetic source
2. Surface measurement — place the Hall probe chip side against the magnetic surface for a reading closer to the measured value
3. Reading stability — use the hold measure value function to keep a reading on the display while the probe is repositioned
4. Peak capture — the peak value function retains the highest reading reached during a scan
5. Unit conversion — 1 mT = 10 Gs; switch the unit keys when working in either system
| Magnetic field | TES10A | TES10B | TES10C |
| Field type | DC | DC | DC and AC |
| Display units | mT | mT and Gs | mT and Gs |
| Resolution | 0.1 mT, 1 mT | 0.01 mT, 0.1 mT | 0.01 mT, 0.1 mT |
| Accuracy | ±2% / ±5% | ±1% / ±2% | ±1% / ±2% |
The model differences above are based on the supplied product data. The TES10B measures DC fields only; choose the TES10C when both DC and AC fields must be measured.
