9532700 Hach Pocket Pro+ Multi 1 Swimming Pooll Water Tester for Conductivity, TDS & Salinity — With Replaceable Sensor
NOT A RETURNABLE ITEM, FINAL SALE
Take the guesswork out of water testing. The Hach Pocket Pro+ Multi 1 Tester (Part No. 9532700) is a professional-grade, waterproof handheld meter that measures Conductivity, Total Dissolved Solids (TDS), Salinity, and Temperature in a single rugged pocket-sized device. Built around a user-replaceable sensor and powered by easy-to-find AAA batteries, this multi-parameter tester delivers fast, lab-quality readings with ±1% accuracy — whether you are balancing a saltwater pool, dialing in a salt chlorine generator, monitoring a cooling tower, or checking source water in the field.
Engineered by Hach, the trusted name in water-quality instrumentation, the Pocket Pro+ line replaces disposable testers and guesswork with a reliable, calibratable instrument that you can clean, recalibrate, and re-sensor for years of service. If you maintain pools, spas, aquariums, hydroponics, or industrial water systems, the 9532700 belongs in your kit.
Why Choose the Hach 9532700 Pocket Pro+ Multi 1 Tester?
- 4-in-1 measurement — reads Conductivity, TDS, Salinity, and Temperature with one probe, so you carry one tool instead of four.
- User-replaceable sensor (Part No. 9532701) — when the sensor wears out, swap it in seconds instead of buying a whole new meter. Lower long-term cost of ownership.
- Built-in performance diagnostics — the meter tells you exactly when it is time to clean or recalibrate the sensor, so every reading is one you can trust.
- IP67 waterproof and it floats — drop it in the pool, the tank, or the sample bucket and it comes back. No more lost meters.
- Large backlit LCD — easy-to-read digits and a bright backlight let you test in low light, plant rooms, and shaded equipment pads.
- Replaceable AAA batteries — no proprietary cells and no waiting on a recharge. Auto-off extends battery life for all-day field use.
- Automatic Temperature Compensation (ATC) and up to 3-point calibration with automatic standard recognition for accurate, repeatable results.
What the Pocket Pro+ Multi 1 Measures
This single instrument covers the four electrochemical parameters that matter most for salt and mineral content in water:
- Conductivity — the fast, reliable indicator of total ion content. Auto-ranging across three ranges from 0.0 µS/cm to 19.99 mS/cm.
- Total Dissolved Solids (TDS) — with an adjustable TDS conversion factor for different water types. Auto-ranging from 0.0 ppm to 10.00 ppt.
- Salinity — ideal for saltwater pools, salt chlorinators, aquariums, and brackish water. Reads 0.00 to 10.00 ppt and 0.00 to 1.00%.
- Temperature — 0.0 to 50 °C, used for ATC and as a stand-alone reading.
Applications & Use Cases
The 9532700 is a versatile workhorse trusted across dozens of industries and everyday water-testing jobs, including:
- Pool & Spa — verify salt levels for salt chlorine generators (saltwater pools), check TDS buildup, and confirm balanced water chemistry.
- Salt Chlorinator Maintenance — keep your salt cell operating in its ideal ppt range to protect equipment and chlorine output.
- Aquariums & Aquaculture — monitor salinity and conductivity for fish, reef, and brackish systems.
- Hydroponics & Agriculture — dial in nutrient strength via EC/TDS for healthy yields.
- Boilers & Cooling Towers — track conductivity and TDS to manage blowdown and scale.
- Drinking Water, Groundwater, Surface Water & Wastewater — field-ready spot checks for municipal and environmental work.
- Beverage, Education & Environmental Testing — reliable readings for QA, classrooms, and research.
Compatibility, Replacement Parts & the Pocket Pro+ / Pocket Pro Family
The 9532700 uses a dedicated replaceable sensor, Part No. 9532701 — keep a spare on hand so you are never down. The tester is part of Hach’s broader family of pocket testers, so you can standardize on one platform across parameters:
- 9532700 — Pocket Pro+ Multi 1 (Conductivity / TDS / Salinity / Temp) — this product
- 9532800 — Pocket Pro+ Multi 2 (pH / Conductivity / TDS / Salinity / Temp)
- 9532000 — Pocket Pro+ pH Tester
- 9531400 — Pocket Pro Low-Range (LR) Conductivity Tester
- 9531300 — Pocket Pro High-Range (HR) TDS Tester
- 9531600 — Pocket Pro Salt Tester
- 9532701 — Replacement Sensor for the 9532700 Multi 1

Frequently Asked Questions
Does the Hach 9532700 test pH?
No. The Multi 1 (9532700) measures Conductivity, TDS, Salinity, and Temperature. If you also need pH, choose the Pocket Pro+ Multi 2 (9532800), which adds pH to the same four parameters.
Is the 9532700 good for saltwater pools and salt chlorine generators?
Yes. It reads salinity from 0.00 to 10.00 ppt, the range used to verify and maintain the salt level your chlorinator needs, making it ideal for saltwater pool and salt-cell maintenance.
Can I replace the sensor instead of buying a new meter?
Yes. The sensor is user-replaceable using Part No. 9532701, which keeps your long-term costs low and extends the life of the instrument.
Is it waterproof?
Yes. The housing is rated IP67 waterproof and floats, so accidental drops into water won’t ruin or sink it.
What batteries does it use?
Four standard AAA batteries (included), which are easy to replace in the field. An auto-off feature conserves battery life.
How is it calibrated?
Up to three points, with automatic calibration-standard recognition and a built-in calibration reminder, plus Automatic Temperature Compensation for consistent accuracy.
