Arrived as expected, packaged well, and the instruction were clear and concise. Unit came with everything needed to start taking readings immediately. Machine is easy to use and so far the readings are inline with its more expensive counterparts. Only a few weeks in to using it, I’ll update as time goes on.

Great reads, easy to calibrate, stays calibrated even in my truck. Perfect complete set for testing. I put in a ph strip container and I have my whole CESCL kit in one case. I use bottled water to rinse and vinegar to clean regularly. Glad I took the chance on the unit.

5.0 out of 5 stars Turbidity Meter Model TU-2016

Very easy to use, precise measurement and all of that for low price.Inspite of it some disadvantages that I found: 1. The capacity of device's memory very low, but for my test work it was sufficient. 2. Box for testing bottles for 0NTU and 100NTU sits to tight so if pull it strongly you may scratch the glass of testing bottles. That's all I have found. Thank You SPER SCIENTIFIC.

This meter worked great. My engineer felt it should be provided on every project as the metric to go by.

(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } Excellent product and price. I have only had this a short time, but my initial impression is good. I compared the results from the meter to lab reported results of several samples collected at the same time and from the same location, and the meter proofed to be accurate. Although not mentioned in the product description it does come with two samples vials, calibration standards (0 and 100 NTU), and a hard case. The case itself is not watertight but it is plenty large for adding additional standards or sample vials.

I have already recommended this item to friends and will again!
