Don't throw away that paperwork that comes with your Hamilton sensor!
The most common requests received by process analytics technical support include additional copies of certificates and documentation for our products. This knowledgebase article details documentation normally included with each product and provides mock examples to help understand the content within each document.
Declaration of Quality
The Declaration of Quality (DoQ) is a final test document. This document includes the product-specific reference number, serial number, and the production lot number. Final testing values are also listed on the DoQ as well as product specifications, firmware versions, and any factory adjustable settings.
Sensor DoQ's are available for download in the certification area of the website. Part number and serial number are needed for this download. DoQ's for liquid standards such as pH buffers and conductivity solutions are also available.
Sensor part number and serial numbers used to download DOQs can be found on the sensor shaft and packaging label
Manuals & Quick Guides
Nearly all products should include some form of instruction manual or quick guide to assist with wiring, installation, calibration, and disposal. Arc sensors have additional Modbus programmers manuals that do not ship with the product but can be downloaded from the Hamilton website.
Products with wetted stainless steel or other metallic components include a material certificate in the packaging. This document confirms the raw barstock / billet that was used to machine the part. Individual alloy components can be verified with the material certificate. This document can be found online using the heat number that appears on the sensor shaft or DoQ document.
The heat number used to find material certificates can be found on the sensor shaft and cap as shown below
Additional documentation such as declarations of conformity, material specifications, and hazardous area approval information can be located on the Quality and Regulatory certification page. SDS (Safety Data Sheets) for chemicals can be found in the download section of the Knowledgebase by searching for document type - SDS. The knowledgebase also has supplementary manuals and other valuable product information available for download.
What's Included? Documentation Examples
pH / ORP Probes
Process sensors with serial numbers typically ship with DoQ and manual. General purpose sensors that are not serialized will ship with a manual only. If the sensor has certification for hazardous areas then a plastic tag with the proper agency classifications will also be included with the documentation.
Optical Dissolved Oxygen Sensors
VisiFerm, VisiPro, VisiTrace, and VisiWater Optical DO sensors all ship with DoQ, manual, and material certificates. The heat number tied to the material certificate can be found on the sensor shaft. A separate heat number for the replaceable sensing cap can be found near the tip on the sensor.
Polarographic Dissolved Oxygen Sensors
OxyFerm and OxyGold dissolved oxygen sensors ship come with DoQ, manual and material certificates. If the sensor has certification for hazardous areas then a plastic tag listing the proper agency classifications will be included. OxySens sensors come with manual and certification tag only.
Most 2-pole and 4-pole Conducell sensors ship with DoQ, manual, and material certificates. Sensors with agency certification will include a tag noting their classification. The Conducell 2DC-PG ships with DoQ and wiring scheme only. The Conducell I Inductive sensor comes with a manufacturer's certificate, wiring scheme, and manuals.
pH / ORP Buffers
pH buffers have two forms of documentation available. Individual buffer bottles ship with a DoQ. The DoQ includes specific information about the buffer and its traceability as Certified Reference Material. The DoQ also includes basic usage instructions. Separately, all pH buffers have representative lot samples tested by a 3rd party accredited laboratory against PTB or NIST reference solutions. Lot certification documents can be obtained from the Hamilton website using the Buffer Solution Lot Number found on the bottle label or DoQ.
Please note that ORP Buffers include test documentation on each bottle thus do not ship with additional certificates or DoQ.
Conductivity standards come with a DoQ document. The DoQ also includes usage instructions and 3rd party testing by DFM, an accredited Danish metrology agency.
