| May 10, 2021, 10:15 am is this probe equivalent to Hanna HI2910? |
| No, wait a minute, I'll give you an equivalent to the HANNA HI2910 |
| May 10, 2021, 10:21 am strange because my microphone plus Regul was delivered with HI2910 |
| Yes, but it depends on the type of fixation (Threading at the top of the probe). |
