Hach BioTector B7000 - Consumables and Analysis Parameters

Page 35
OPTIONAL FEATURES
Result Output: TIC, TC, VOC, TN, after correlation COD, BOD
Remote Control: Input for remote start / standby
Input for remote stream and range selection
Input for remote manual grab sample analysis
Network Control Unit for remote access over Internet or Intranet connection
using HTTP over TCP/IP protocol
Industrial Interface: Modbus, Profibus, Ethernet
(when any of the Modbus, Profibus or Ethernet option is selected, the digital
output signals are sent through the relevant device with its specific
communication protocol)
Calibration & Cleaning: Valves for Automatic Calibration and Sample Line Cleaning
Multi-stream: Valves for up to 6 streams with up to six 4-20mA signals
The number of available outputs depends on the manual stream
configuration.
Manual stream: Valves for up to 6 manual streams with up to six 4-20mA signals
The number of available outputs depends on the multi-stream configuration.
4-20mA Outputs: As individual signal up to maximum of 6 or as multiplex signal up to maximum
of 35. Maximum impedance: 500 ohms.
Hazardous Area: Certification options are available to European Standards (ATEX for Zone 1
and Zone 2) and to North American Standards (Class I Division 1 and Class I
Division 2). Other options are available on request.
CONSUMABLES Typical Replacement Frequency & Consumption
Acid & Base: 3 - 10 weeks/25 Liters (application dependent)
TN Cleaning Solution: 45 - 90 weeks/10 Liters (application dependent)
Deionised Water: 12 - 25 weeks/10 Liters (application dependent)
Oxygen: Average consumption is 22 L/hour (367 ml/min)
Integrated and external oxygen concentrator options are available.
Service: 6 Monthly Intervals
ANALYSIS PARAMETERS
Oxidation Method: Patented Two-Stage Advanced Oxidation Process using Hydroxyl Radicals
TOC Measurement: NDIR measurement of CO
2
after oxidation
TN Measurement: Direct photometric analysis of Nitrate after oxidation
Measurement Terms: TOC (Total Organic Carbon) including Non-Purgeable Organic Carbon
(NPOC) and Purgeable Organic Carbon (POC)
BioTector TIC&TOC mode measures NPOC.
BioTector VOC mode measures TOC as NPOC+POC.
Measured Components: TOC (NPOC)
