Two Types of Water-Quality Instruments

  1. Chemical & Reagent Manufacturers provide instrumentation as delivery systems for their products. Think about the low-cost printer that makes 20-30 times the price of the device on replacement ink cartridges.  The primary function of these instruments relies on chemicals that need to be replaced on a regular basis.  While some technology requires this, others do not.  Often, suppliers will offer the equipment at a reduced price in exchange for a chemical contract.  While up-front costs may be more attractive, long-term costs may be higher.  Check your budget.
  2. Equipment Developers work on the innovative technology. Reagents and supplies are secondary for use in support of the instrument. Many new instruments operate without consumables.  There are exciting new designs that simplify measurement, reduce cost of ownership, and eliminate maintenance.  These are worth investigating.
