This Hanna turbidity / chlorine meter uses a tungsten light source for consistently reliable readings and feature an EPA compliance reading mode. The backlit LCD is easy to read. The light detector used for turbidity readings is a silicon photocell. Free and total chlorine readings are given by a silicon photocell with 525nm narrow band interference filters. Data you have logged can be downloaded through either the RS-232 or USB interfaces. The Tag Identification System (TIS) allows you to record the time and place at unlimited specific measurement locations. Just add iButton® tags near your sampling sites and then use the Meter to identify and authenticate logged data by touching the iButton to the connector on the Meter. Use the Windows® Software to sort or filter all collected data using different criteria-such as specific sampling location, parameter, date and time intervals or fixed range-to filter measured values. Data can be plotted in a graph, exported to other programs or printed. Compliance: USEPA 180.1.
This turbidity / chlorine meter utilizes an EPA compliant tungsten light source and state-of-the-art optical system that allows consistently reliable and accurate measurements for free and total chlorine as well as 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. HI 93414 meets all EPA requirements with regards to the Standard Methods for Turbidity and Colorimetric Chlorine Measurements.
Turbidity is measured up to 1000 NTU and free and total chlorine measurements can be made in the 0.00 to 5.00 mg/L (ppm) range. Depending on the measured sample and required accuracy, users can select normal measurement, continuous measurement or signal averaging.
HI 93414 features the ability to use 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 isn't 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 startup, 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 instrument is equipped with backlighting. The current date and time can be displayed on the LCD.
