Eutech PCSTestr® 35 Multi-Parameter Pocket Tester

Eutech PCSTestr® 35 Multi-Parameter Pocket Tester

The Eutech PCSTestr® 35 is a professional-grade 5-in-1 waterproof pocket tester designed to measure pH, Conductivity (EC), Total Dissolved Solids (TDS), Salinity, and Temperature with exceptional accuracy. Combining multiple water quality parameters into a single compact instrument, the PCSTestr® 35 is ideal for laboratories, water treatment facilities, environmental monitoring, hydroponics, aquaculture, food processing, and industrial quality control. Its rugged IP67 waterproof construction, user-replaceable sensor, and advanced calibration capabilities make it a dependable solution for both field and laboratory testing.  

Key Features

• 5-in-1 Multi-Parameter Measurement: Measures pH, Conductivity (EC), TDS, Salinity, and Temperature using a single handheld instrument.
• High-Precision pH Measurement: Measures pH from 0.00 to 14.00 with 0.01 pH resolution and ±0.01 pH accuracy.
• Multi-Range Conductivity Measurement: Automatically measures conductivity from 0.0 to 199.9 µS/cm, 200 to 1999 µS/cm, and 2.00 to 20.00 mS/cm.
• Wide TDS Measurement Range: Measures 0.0 to 99.9 ppm, 100 to 999 ppm, and 1.00 to 10.00 ppt with an adjustable TDS conversion factor (0.40–1.00).
• Advanced Salinity Measurement: Measures salinity up to 10.00 ppt or 1.00%, making it suitable for freshwater and light saline applications.
• Automatic & Manual Temperature Compensation: Supports both ATC and MTC for improved measurement accuracy.
• 5-Point pH Calibration: Supports up to 5 automatic calibration points with USA and NIST buffer recognition.
• 3-Point EC/TDS/Salinity Calibration: Provides enhanced accuracy through multiple calibration options.
• Large Dual LCD Display: Simultaneously displays measurement values and temperature for easy reading.
• IP67 Waterproof & Floatable: Waterproof housing is designed to float if accidentally dropped into water.
• User-Replaceable Sensor: Sensor replacement requires no tools, reducing maintenance costs and downtime.
• One-Touch Parameter Switching: Quickly switch between pH, EC, TDS, Salinity, and Temperature with a single button.
• Long Battery Life: Operates for more than 150 hours using four A76 alkaline batteries.
• Auto Power-Off & Non-Volatile Memory: Saves battery power while retaining calibration settings even after battery replacement.
