Berthold LB6500-3-H10 dose rate probe

The LB6500 – H10 is a Geiger-Mueller dose rate probe for use in a variety of radiation protection applications; a dose rate probe for environmental gamma monitoring or local dose rate measurement.
The measured quantities are the environmental dose equivalent H*(10) and the environmental dose rate equivalent Ḣ*(10).
Dose rate probes are available in 2 versions:
1. LB 6500-4-H10 low dose rate ≤ 10 mSv/h
2. LB 6500-3-H10 high dose rate ≤1 Sv/h
