Refurbished DirectSense I Classical Probes
A large number of customers have added the new DirectSense II probes to existing GrayWolf systems, while many have taken advantage of GrayWolf’s trade-up program and traded in DSI probes for DSIIs. In addition, many DSIs are being retired from our demo/rental pool which is now primarily populated with DSII units. There are some really large discounts available for demo/rental pool units, dependent on age. Refurbished meters and probes are always available with updated factory calibration and with a full one-year warranty. Contact SalesTeam@GrayWolfSensing.com for a quote to supplement your existing fleet, or to get started with GrayWolf quality equipment on a smaller budget.
