## Questions & Answers

**Q: How long does the probe last? Do you get to replace it often like you do with Bluelab?**

The lifespan of the probe depends on a variety of factors such as frequency of use, proper storage, regular cleanings and other common best practices for maintaining pH electrodes. The HI9814 has an on-screen indicator that provides visual confirmation that your probe is working at its best. Our probes are designed with the grower in mind and the HI9814 has a 2 year warranty while electrodes and probes are warranted
for a period of six months.

**Q: Is display backlit**
A: Yes

**Q: Does this measure OPR?**
A: No it does not.

**Q: How does this compare to bluelab's combo meter?**

High quality.....reliable!!! I recommend it!🤙

### ⭐⭐⭐⭐⭐ Best combo meter on the market
*by D***V on December 18, 2024*

### ⭐⭐⭐⭐⭐ Great Meter all in 1
*by M***E on December 15, 2019*

This is the easiest meter I've used yet. I also have the groline version below this which is the stick kind ($209 model) and this is worth the extra money so far because you dont have to stick your head in the reservoir to try and see the reading. This one also has a bright backlit display unlike the other model and seems to hold calibration longer.
