Unreliable and Inaccurate

Based on our own experience using this substance analysis instrument, we found it to be consistently unreliable and inaccurate in its readings. While the compact size is a plus, it falls short in terms of quality and dependability.

Pros
  • Compact size
Cons
  • Unreliable, inaccurate readings

Farm representative recommended

Great product, I called our local farm representative and found this product to be the best for determining oxygen levels in ponds with crayfish and catfish. Waterproof and durable. Just make sure the tip stays wet. We've only had the counter a few weeks, but it's holding up well.

Pros
  • Backlit LCD screen for reading in dark or dimly lit areas
Cons
  • Crumpled packaging

Good product! I've had mine since '07 and right now.

Great Product! I've had mine since '07 and only recently stopped working. This thing has been working day and night on a shrimp farm in the toughest conditions for the last 8 years. Great buy if you're considering something really heavy.

Pros
  • Handheld Dissolved Oxygen (DO) and Temperature Meter for on-site measurement of dissolved oxygen in fresh, marine or polluted water
Cons
  • New Competitors
