Alat Laboratorium COD Meter Instruments Komplit dari Hanna Instruments

HI 83099 is one of the most versatile photometers on the market. In addition to COD, this meter measures up to 47 of the most important water quality parameters. The HI 83099 operates in three different ranges to cover virtually every COD application. 

• Easy COD measurement
• Outstanding measurement quality
• Save space in your laboratory
• PC compatible
• 47 methods

HI 83099 is one of the most versatile photometers on the market. In addition to COD, this meter measures up to 47 of the most important water quality parameters using liquid or powder reagents. The amount of reagent is precisely dosed to ensure maximum reproducibility. HI 83099 bench photometer can be connected to a PC via a USB cable. The optional HI 92000 Windows® Compatible Software helps users manage their data. HI 83099 features a powerful interactive user support that assists the user during each step of the analysis process. A tutorial mode is also available in the Setup Menu.

 • Low temperature alert
Appears when the block is warming up. It alerts the user that the temperature is
below the set value.
• High temperature alert
Appears when the block is warming up. It alerts the user that the temperature is above the set value.
• Countdown timer
Shows time remaining until the heating element shuts off.

The HI 839800 COD reactor is constructed of durable materials. The aluminum block incorporates a 25-vial capacity and a well for a reference temperature probe. The HI 839800 COD reactor is an easy to use test tube heater. Its well-marked user interface provides intuitive operation. The reactor is equipped with two predefined temperature settings: 150º and 105ºC. COD and total phosphorus digestions are conducted at 150ºC, and total nitrogen digestions are at the 105ºC.

In addition, the HI 839800 has 3 LED’s for visual indication. A green LED indicates power, a blinking red LED warns the user of a hot heater block (above 50ºC), and a yellow LED indicates heating. A three hour countdown timer is also incorporated to control timed digestions. When the countdown timer expires, a beep will sound and the heating element will turn off.

The reactor contains a thermal fuse that prevents overheating by turning off the heating element. Block tempertaure is continuously displayed on the LCD even when there is no active temperature program running.

• Three measurement ranges to satisfy each need
As COD levels vary depending on the application and process
measuring points, HANNA offers reagents to cover three separate
ranges. Simply choose the best range for the application:
low range: 0 to 150 mg/L O2
medium range: 0 to 1500 mg/L or 0 to 1000 mg/L O2
high range: 0 to 15000 mg/L O2

• Accurate and repeatable measurements
HANNA COD reagents have been developed in accordance
with Standard Methods 5220D, USEPA 410.4 and ISO 15705:2002
methods.

• Pre-dosed vials
HANNA vials contain approx. 3 mL of pre-dosed reagent. The
operator just needs to add a small quantity of the sample - 2 mL
for LR and MR, and 0.2 mL for HR analysis.

• Quick and accurate measurements
With pre-dosed vials, test preparation time is dramatically
reduced. There is no time-consuming reagent preparation
procedure or glassware cleaning.

• Safe reagents
HANNA COD reagents are safe for operators and the
environment. Vials and caps have been designed to avoid
accidental reagent spills. Due to the pre-dosed reagents, the
amount of chemicals is minimized.
