## Questions & Answers

**Q: Does it come with barbs or hose clamps?**
A: No, it does not come with hose clamps.

**Q: For 1/2" silicone tube, would 3/8" posts be a good snug fit?**
A: Nope.  You want the 1/2" ThruMometer.  When we talk about tubing the diameter is the ID, or inner diameter.  When we talk about the barbs, we want the OD, or outer diameter.  So for 1/2" silicone tubing you want 1/2" barbs, and for 3/8" silicone tubing you want 3/8" barbs.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Handy Thermometer for Transferring Beer
*by J***N on March 23, 2018*

This has been very handy when transferring beer from my kettle to my fermenter after the counterflow chiller. I've found the temperature to be accurate enough to identify when my wort is at a safe temperature for yeast pitching before pumping into my fermenter. Saves a little time rather than constantly checking with a thermometer.

### ⭐⭐⭐⭐⭐ Good purchase
*by M***R on January 14, 2019*

Good thermometer. Used post chiller to evaluate wort temp. So far so good

### ⭐⭐⭐⭐⭐ Five Stars
*by A***E on May 4, 2017*
