Portable Automatic SDI Tester - Simple SDI

Simple SDI Automatic Tester Features

• Rugged Crush-Proof Carrying Case: durable protection for the meter, withstands harsh field conditions.
• Pressure Gauge: Accurate, easy to read.
• Full Port ½” Ball Valve: Minimal pressure drop – allows testing on as low as 35 psi feed pressure.
• Microprocessor Based Controller: Highly accurate and easy to use
• SeaWater Compatible: Fully non-ferrous water path is compatible with sea water and other corrosive waters. 
• Clear, easy to read LCD display prompts the operator through the test procedure and displays current test data while silt density index tests are underway.
• Audible alerts notifies the operator at the end of the silt density index test as well as if any errors have occurred.
• In-field calibration and repair. Modular design for easy field repairs. Sensor calibration is easy to perform in the field.
• Rugged, durable, reliable. Carefully selected components ensure years of trouble-free silt density index testing.
• Linear, precise pressure regulation for accurate results even on high SDI waters. Provides set-it-and-forget-it convenience.
• Built to the ASTM D 4189-07 standard for silt density index testing accuracy and repeatability greatly exceed the criteria of the silt density index standard.

• Weight:  6 lbs (2.7 kg)
• Battery Type:  6 volt, 3000 mAH Lithium Polymer (LiPo)
• Battery Life:  At least 5 years of typical usage.  (Over 300 full charge cycles)
• Battery Capacity:  Approximately 30 hours of testing.
• Power Supply:  5VDC, USB-A Port charger, (e.g. phone, tablet or other devices charger (user supplied))
• Operating Pressure: 35 – 100 psi
• Temperature: 35 – 100°F

New and Improved Simple SDI version 2.0 is the direct replacement for the original Simple SDI, which was retired in 2020.

New and improved features of Simple SDI 2.0 include:  

• New Lithium Polymer battery for more tests per charge, lighter weight, longer life, and universal voltage. USB charging cable is included.
• New built-in prefilter to ensure that the flow sensor is protected from particulates.
• New dual pressure regulator design provides safe operation up to 100psi and improves accuracy by regulating the pressure to the test regulator.
• Improved controller now has backlit LCD, real time clock, data storage, and USB computer interface.
• Watertight enclosure (IP66/67) protects electronics.
