Product Description

The Oakton 35462-50 EcoTestr Salt is a handheld, waterproof and dustproof pocket meter that measures salinity and floats, if dropped in liquid. A portable pocket meter is commonly used to measure the salinity of substance in aquaculture, aquariums, fish ponds, food processing, swimming pools, and in environmental treatment. This meter has ATC for accurate readings in fluctuating temperatures, and push-button calibration for a wide range of results. It features a transparent, protective cap to reduce contamination and protect the sensor. The cap keeps the sensor moist when stored upright, and can be used as a container for sensor-conditioning, or on-site calibration. The meter’s waterproof and dustproof housing has IP67-rating for protection against solid objects or liquids. Its stainless steel sensor tip is both durable and chemical-resistant. The meter has a large, upright, single-line LCD screen for ease of viewing, a hold function which freezes readings for recording, and an auto shut-off to extend the life of the batteries. It has a click-lock battery cover for battery access to replace batteries without tools.

The 35462-50 pocket meter comes with an integral stainless steel sensor, has ATC from 0 to 50 degrees C (32 to 122 degrees F), and operating temperature of 0 to 50 degrees C (32 to 122 degrees F). Salinity range is 0 to 10.00 ppt, resolution 0.1 ppt, accuracy + or - 1% full-scale (+ or - 2% above 5 ppt). Its dimensions are 1.25 (l) x 1.5 (w) x 6.5 (h) inches (3.2 x 3.8 x 16.8 cm) and it weighs 3.25 ounces. The testr works with four 1.5-V alkaline batteries (not included) for up to 500 hours of continuous use (Eveready A76 or LR44 replacements).

Salinity is the amount of alkali metal salts or magnesium salts in a substance. Salt meters are commonly used by researchers, manufacturers, and hobbyists in aquaculture, agriculture, hydroponics and water-testing, and for scientific applications.

I was a bit hesitant to buy this salt tester because of the low price but with Amazon's awesome return service I went ahead and gave it a try knowing I had nothing to lose. My intended use for this tester is for my salt water pool which I need to drain and refill in the next week, and upon filling it again, I need to know with confidence what the salinity level is so that my chlorine generator works properly.

In the past 3 days I have taken a water sample to 3 reputable pool stores in my area and they all said my salinity was over 4000ppm and less than 4300ppm. This tester, after a couple swirls and resting in the sample water, displayed a reading of 4100ppm.

It's only the first day of use but I would recommend this to anyone that only needs an accurate salt reading from a digital tester and nothing else.

Up to the task, fast, and most importantly, it agrees with my salt cell. Do not forget to do the initial calibration step with tap water.

We bought this for my In-Laws for Christmas, as they had just converted their pool from chlorine to a salt system. We calibrated it to the pool tech's meter when he stopped by, and my Father-in-law is quite happy with the device's ease of use. Scored points with the Father-in-law - can't beat that!

The product stopped working after 2 months. The seal around the batteries is bad and water can get in and corrode the battery area.
It takes 4 battery s to run this product at a cost of $4.99 per battery. The product was not worth the money I have spent on it.

I bought this back in 2012 and recently decided to try it again now that I know quite a bit more about my salt water pool chemistry.

I don't trust it's reading and here's a three part test I just did:

1. Jandy Aquapure Salt Water Generator (SWG) Unit shows 3000 ppm of salt. Apparently these SWG units can be off by ~ 300 ppm. I can live with that variation.

2. This Oakton unit shows 2100 ppm and the next day 2600 ppm. PPM converted from readout of PPT.

3. The Taylor Salt Water Test Kit K-1766 shows 3600 ppm. Note: If you're not familiar with the Taylor test kits for pools, industry experts believe they're the most accurate for testing Alkalinity, PH, Salt, etc.

I'm most likely going to try to calibrate this Oakton unit to 3600 ppm today.

Much to my dismay when I called the Oakton Technical Support hotline on Friday July 18th, the "tech" couldn't tell me what the start up display should show upon powering the unit. Really? Seems simple enough as mine shows 1.8.8.8 and r 1.0 upon start up with no water. Is that normal? I don't know but I've posted that question to Amazon. Perhaps some knows.

My advice: Save your money and buy the Taylor Sodium Chloride (Salt Water) Test Kit K-1766 as I did. Found my via Amazon for $16.00 bucks + shipping which was $23.00. Easy and accurate.

This unit does a great job of analyzing Total Dissolved Solids (TDS), which includes dissolved salt (sodium chloride) as well as all other dissolved solids and ionic species. Over time, TDS (non-salt TDS) builds up in a pool to the tune of several thousand parts per million (ppm), which is not necessarily a bad thing. Note - these hand-held units typically read out in parts per thousand (ppt), where one ppt = 1000 ppm. You want about 3 ppt (3000 ppm) of sodium chloride in the water. In a freshly filled pool (public water), this will usually be equivalent to a TDS of about 3.2 ppt (3,200 ppm). But after a few years, the TDS level, as read by this meter, will likely be substantially higher than the sodium chloride concentration. Oakton (sometimes branded by Haward) makes another meter that is specific to sodium chloride. It has the word "Salt" on the front of it (as opposed to TDS or TDS/Low or TDS/High). That's the one you want if you're just using it to validate your salt chlorinator's built-in readout. In my experience, when the chlorinator is working correctly, the built-in readout is actually pretty accurate.

Received in the mail today. It's very easy to set up.
The Jandy AquaPure on my pool was telling me the salt concentration was 4600ppm.
I put the Oakton EcoTestr into the water and in 2 seconds it popped up 4600ppm.
Can't beat that!
By the way, I know that's too high for a swimming pool. That's why I bought this device, to double
check my AquaPure as I adjust down my salt.
For the price, this device can't be beat. Comparable handheld devices cost 5X as much.
I can't promise it's going to last because I've only had it for 1 day, but so far it's excellent.
And at the price, even if it last half as long as one that's $300, it's still a better deal.

I work in the swimming pool service industry. I need to test salt quite often and although this product provides a fairly accurate estimate most of the time, the quality is horrible. The first year my tester stopped working half way through the summer. The second year I bought 2 more to have one as a backup. I take excellent care of them (keeping them in a protective case that is breathable), bring them inside for the Winter. This Spring, both units didn't work (displayed bizarre readings and the other was completely rusted out where the batteries were). Never buying these again.
