One of the few at this price level that gives real time ppm readings along with alert level notifications. Only downside, it's a little bulky, but the performance offsets that minor issue. Review: Battery died in first one, but it was replaced quickly with minimal fuss by the manufacturer. - Rechargeable battery went dead (would not charge) just after the one year warranty expired. ***UPDATE 10/11/19*** I contacted the company I ordered from and told them what happened and they replaced the unit even though it was a bit out of warranty. The new one is working great. I am happy. ## Features - 🔬 ACCURATE: Hydrogen Sulfide Meter 0-100ppm with 0.1ppm resolution. USA NIST Calibration.

Do you need both items to monitor H2S in the air?** A: No you dont. If you just want to monitor the air in ambient conditions, like in a room, then simply placing the detector and registering results is OK. However in some cases, where there are isolated spaces or in toxic spaces (large drains) where it may be dangerous for one to walk in with the detector, a gas sampling probe would be warranted in such a case to sample the air from the "danger zone" and draw it to the detector which would be in the "safe zone". Thanks, Sarah Kong (FORENSICS via Amazon.com) **Q: Can i use it to detect H2S on water well?** A: Indeed you can! But you will need the pump to draw the sample and have a long tube down to the well. **Q: How big** A: The product is handheld with reasonable dimensions of 110*60*30mm, 134grams **Q: My charger for this broke, what type of charger do I need to buy for this** A: You can use any USB charger, like your phone USB port. Or simply email us and we can send you a replacement immediately. Thank you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great H2S Monitor *by C***E on September 3, 2020* Very impressed with the performance and accuracy of this monitor.
