Berthold  LB 6500-H10 is a dose rate probe in a stainless steel cylindrical shape, which also serves as a handle. The unit is integrated with Geiger-Mueller counter tube, amplifier–pulse shaper stage and high voltage module, used in various radiation protection applications, for environmental gamma-monitoring, and for local dose rate measurements. The measured radiation quantity is ambient dose equivalent H*(10) and ambient dose rate equivalent Ḣ*(10).

The measuring results of the Berthold LB 6500-H10 are displayed on the easy to operate  universal monitor Berhold LB 134 (UMo II) which comes with a data storage system and USB interface. The probe can be used also in combination with the stationary data logger Berthold LB 115, which is a modern and versatile unit with colour display that shows current numerical and graphical values of on-site measurements.

The highest sensitivity of the counter tube is perpendicular to the longitudinal axis. The centre of the active area is marked by a blue ring on the probe case. Due to this quench, the counter tube should always be held vertical or transverse to the radiation incident direction.

The Berthold  LB 6500-H10 dose rate probe exists in 2 versions:

• LB 6500-3-H10 High dose rate ≤ 1 Sv/h
• LB 6500-4-H10 Low dose rate ≤ 10 mSv/h
