Turbidity meter

EHI98703 portable turbidity meter utilises an EPA compliant tungsten light source and state-of-the-art optical system that allows consistently reliable and accurate measurements for turbidity. Users will appreciate the accuracy and sensitivity of this instrument, particularly at very low turbidity levels.
To meet EPA reporting requirements, these instruments have an EPA compliance reading mode. EHI98703 meets all EPA requirements with regards to the Standard Methods for Turbidity Measurements. Turbidity is measured up to 1000 NTU. Depending on the measured sample and required accuracy, users can select normal measurement, continuous measurement or signal averaging.
EHI98703 can be equipped with HANNA's (optional) Tag Identification System (TIS), which allows users to record the time and location of a specific measurement or series of measurements. Logged data can be downloaded to a PC through either USB or RS232 connections.
Reliable performance of the instrument is validated using Hanna's exclusive Cal Check® system and our ready-made, NIST traceable chlorine standards. For turbidity, a two, three or four-point calibration is available using pre-set or user defined standards. Frequent calibration is not necessary as the system compensates for variations in the intensity of the light source.
The instruments' Good Laboratory Practice functions allow traceability of calibration conditions including the time, date and last calibration points.
At start-up, the meter displays the percentage of remaining battery life. A 'low battery' warning message is also displayed on the LCD to avoid unexpected battery failure. This instruments is equipped with backlighting. The current date and time can be displayed on the LCD.

EHI98703 is supplied with:
Five sample cuvets and caps
Calibration cuvets (HI 98703-11)

Photometer with calibration check

Phosphorus is found in nature as phosphates. Its concentration in water is monitored because it causes corrosion when present in high levels. It is also an important parameter for the growth of microorganisms and algae, which are often unwanted in tanks and reserves of water. Phosphorus is an essential element for plant growth and is needed in large amounts. EHI96706 measures the phosphorus (P) content in water samples in the 0.0 to 15.0 mg/L (ppm) range. EHI96706 uses an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell.

Digital refractometer

These digital refractometers are rugged, portable, water resistant (IP65) meters which employ the measurement of refractive index to display the sugar content in samples. Samples are measured after a simple user calibration with deionised or distilled water. Within seconds the instrument measures the refractive index of the sample and converts it to % Brix concentration units. Digital refractometers eliminate the uncertainity associated with mechanical refractometers and are portable for measurements in the field.
The measurement technique and temperature compensation employ the methodology in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis).
Temperature (in °C or °F) is displayed simultaneously with measurement on the large, dual level display along with other helpful message codes.
The wide range suits most applications and the meters are easy to operate. Fill the sample well with distilled or deionised water and press the ZERO key. Place a few drops of the sample in the well and press the READ key. Temperature is automatically compensated (ATC). The refractometers are operated by a single 9V battery for portability and the dual-level LCD displays the measurement as well as temperature readings simultaneously in approx. 1.5 seconds.
Note: EHI96811 wine refractometer can only measure grape juice, not finished wine, as the alcohol in the wine affects the Brix reading.
EHI96801 and EHI96811 are supplied with (1) 9V battery and instructions.

Hygrometer with calibration data logging

EHI9564 and EHI9565 are two new portable thermo-hygrometers designed to provide excellent performance in harsh environments and poorly lit areas.
A microchip built into the RH probe, HI 70602, can store calibration data. When the probe is connected to another hygrometer, the microchip transfers the stored calibration data and eliminates the need to recalibrate the instrument.
Both instruments feature auto-off after 20 minutes of inactivity, temperature readings in Celsius and Fahrenheit, and on-line help to indicate anomalies and direct procedures.
In addition to RH and temperature, EHI9565 will display the dew point with the press of a button. The dew point indicates the presence of water vapour in the air at a given temperature. With this feature EHI9565 permits useful and rapid environmental monitoring where a controlled microclimate is necessary, like greenhouses, museums, clean rooms and laboratories.
Both hygrometers are supplied with HI 70602 RH probe, battery, blue protective case and instructions.
