The LB 6500 is a Geiger-Mueller Dose Rate Probe used in various radiation protection applications. The measured quantity is ambient dose equivalent H*(10) and ambient dose rate equivalent Ḣ*(10).
Dose rate probe in stainless steel envelope with integrated Geiger-Müller counter tube, amplifier-pulse shaper stage and high voltage module.
The dose rate probe exists in 2 versions:
The Geiger-Müller dose rate probe LB 6500 contains the following modules:
The LB 6500 dose rate probe has a type approval (PTB-Bauartzulassung) in combination with the LB 111 Micro Gamma data logger electronics:
