Teletector 6112AD microprocessor controlled dose rate meter with telescope for measuring photon radiation (gamma and X-radiation)
The Teletector 6112AD is a new development of the old Teletector versions, combining the best and most loved features with more reliable electronics.
- Safety by distance: Stainless steel telescope may be extended continuously up to a total length of approximately 4m.
- Wide dose rate range from 0.01 μSv/h to 10 Sv/h with automatic range selection and automatic switching between the two counting tubes.
- Simultaneously measures current, average, and maximum value of dose rate.
- One freely programmable alarm threshold for each dose and dose rate, programming mode to customize operation to individual requirements.
- Continuous monitoring of counting tubes and batteries.
- LCD with analog and digital indication and automatic backlight, speaker to guide the user and emit warning tones.
- Archive containing data of the last 496 Teletector uses.

Teletector 6112AD features
Two GM counting tubes serve as detectors allowing a very wide dose rate range up to 10 Sv/. The counting tube probe is mounted at the end of a stainless steel telescope which can be continuously extended up to approximately four meters. This allows measurements at large safety distances and at places difficult to reach. Automatic range selection and automatic counting tube selection is what you expect from a modern instrument. The Teletector’s design emphasizes high versatility without neglecting clearness and ease of operation.
The Teletector’s design also emphasises low energy consumption at still high comfort. A light sensor automatically controls the white LCD backlight according to ambient light conditions. This makes the display easy to read in complete darkness as well as in direct sunlight.
The connector at the side of the Teletector’s housing provides a 5 Volt supply output and a serial interface. External probes of the AmSeL or a PC can be connected to exchange data according to AmSeL rules.
