HORIBA LAQUAtwin 4EC-33 – Conductivity, TDS and Temperature Meter
The HORIBA LAQUAtwin 4EC-33 is a portable conductivity, TDS and temperature meter designed for fast and simple measurements directly from the sample.
Its compact pocket-sized design integrates the sensor, display and measurement area into one practical instrument, allowing measurements to be performed using a very small sample volume.
Conductivity, TDS and temperature measurement
The main advantage of the LAQUAtwin 4EC-33 is its ability to measure three parameters with a single instrument:
- Electrical conductivity (EC)
- Total dissolved solids (TDS)
- Temperature
Wide conductivity range
The LAQUAtwin 4EC-33 uses a 4-electrode measurement method and provides a conductivity range of up to 199.9 mS/cm.
- 0 to 199 μS/cm
- 200 to 1999 μS/cm
- 2.00 to 19.99 mS/cm
- 20.0 to 199.9 mS/cm
TDS measurement up to 9990 ppm
The LAQUAtwin 4EC-33 includes TDS (Total Dissolved Solids) measurement, allowing total dissolved solids values to be obtained from measured conductivity.
- 0.0 to 99.9 ppm
- 100 to 999 ppm
- 1000 to 9990 ppm
Four TDS curves
The 4EC-33 provides several TDS conversion curves:
- TDS Factor, adjustable from 0.4 to 1.0.
- EN 27888.
- 442.
- NaCl.
Temperature measurement
The HORIBA LAQUAtwin 4EC-33 measures sample temperature from 0 to 50 °C and features automatic temperature compensation.
Up to 4-point calibration
The LAQUAtwin 4EC-33 supports up to 4-point calibration and automatic recognition of calibration standards.
Recognised standards include:
- 84 μS/cm
- 1413 μS/cm
- 12.88 mS/cm
- 111.8 mS/cm
Only 0.12 mL of sample
Only 0.12 mL of sample is required for measurement, making the instrument particularly useful when sample quantities are limited.
Replaceable sensor
The instrument features a replaceable sensor, simplifying maintenance and helping extend the service life of the meter.
IP67 protection
The LAQUAtwin 4EC-33 features IP67 protection, making it suitable for laboratory and field applications.
Applications
- Water quality control
- Drinking water
- Laboratories
- Pharmaceutical industry
- Semiconductor industry
- Food and beverage industry
- Agriculture
- Aquaculture
- Boiler feed water
- Total dissolved solids testing
