Welcome to the Home Page of RL Instruments, Inc.

For the past 15 years RL Instruments has specialized in helping our customers choose the right measurement and control testing instruments for both on-line and bench top applications. We also carry a full line of refractometers and almost any measurement and control instrumentation made, even though it may not be on our website.  We install custom laboratories to the customers specification.  In short, we can supply a laboratory from the ground up with all instrumentation and consumables in a convenient one stop shop with no long delays - and we can do it for small operations all the way up to billion dollar per year giants.

Do you have a pH measurement need where you cannot find an instrument that will apply?  Do you have to move pH measurement to the process, but have avoided doing so due to glass pH probes?  Are you in need for a very small pH or pressure sensor of negligible weight?  Do you need a refractometer that is a precision digital instrument rugged enough for production floor environments?  If any of the above apply - a consultant at RL Instruments can assist you in choosing the right instrumentation to suit your budget and usage needs.  RL Instruments offers 24 hour customer support - and exclusive "Lifetime Loaner Service" for most of the instrumentation that we offer.  Our motto is "It's service AFTER the sales that counts!"
