HI8734

Description

The HI8734 is a rugged, portable TDS meter designed for use in a wide variety of environmental conditions. It is supplied with a four-ring conductivity probe to allow for three ranges of measurement. TDS readings are adjusted with manual temperature compensation, assuring users of consistent and accurate measurements of total dissolved solids.

  •  Four-ring probe
•  Manual Temperature Compensation
•  Three measuring modes

The measurement of total dissolved solids (TDS) indicates the amount of ions dissolved in a solution. The Three Range Portable TDS Meter – HI8734 is suitable for use in the water conditioning industry, but particularly in the softening, demineralization, reverse osmosis, and drinking water applications. It offers three measurement ranges from 0.0 mg/L to 19.99 g/L with a ±1% FS accuracy. The HI76301D four-ring probe that is supplied with the meter allows for a wide range of measurements with a single sensor.

 Features at-a-glance
Four-ring Probe
•  The four-ring probe that comes with the HI8734 offers a versatile and accurate solution for TDS readings.
•  Four ring technology allows for a larger range of measurement within a single probe, whereas two probe technology is somewhat limited in the range in which it can measure.
  •  The probe comes with a protective PVC sleeve that assures durability when taking measurements outdoors.

Manual Temperature Compensation
  •  Since temperature has such a dramatic effect on conductivity readings, having a meter that offers temperature compensated readings is invaluable.
•  Once measured with an accurate thermometer, the temperature of the sample can be input on the meter using the temperature knob.
•  The meter then accounts for the effects of temperature on the sample’s TDS reading in the range of 0 to 50°C (32 to 122°F).
•  The temperature compensation coefficient, also known as β, is set at 2%/°C; this factor corrects the reading 2% for each degree Celsius change in the sample.

  One-point Calibration
  •  The HI8734 can be calibrated at one point in a standard TDS solution.
•  The calibration knob located on the face of the meter is easily adjusted to the correct calibration standard.

  TDS Factor
  •  The TDS value in aqueous solutions is directly proportional to conductivity.
•  The ratio between the two parameters depends on the solution being measured.
•  The HI8734 has a set TDS factor of 0.5 that is common for many solutions, meaning that 1 μS/cm is equal to 0.5 mg/L (ppm) of TDS.

  Three Measurement Ranges
  •  HI8734 offers three TDS measurement ranges. Each range has a dedicated button on the face of the meter, allowing users to easily switch between ranges when necessary.
•  The meter is programmed to let the user know when their current reading is out of range, and a new range should then be selected.
