Why Rent Validation Equipment for Chamber Mapping?

Estimated reading time: 4 minutes

Masy BioServices has rented, sold, and calibrated validation and metrology equipment for many years. Customers often ask various questions about what these instruments can do, and for best practices on how to use them for temperature and RH mapping in GMP chambers. We decided to share some of the most common questions and our answers to help you streamline your validation process and ensure accurate results.

Why should you rent validation equipment for chamber mapping?

  • You have been trained to use validation test equipment and your company doesn’t own a validator, bath, standards, and sensors (temperature, RH, CO2)
  • You are planning a shutdown or a large project and need multiple sets of validation equipment in a tight timeframe
  • The equipment your company owns is dedicated to other projects, out of service or being calibrated when you need it
  • You don’t have capital funds to purchase and renting is an expense you can afford
  • Your company owns older, unreliable, non-compliant or obsolete equipment and you want to “test drive” newer efficient equipment as an evaluation plan to consider future project purchases

Should you rent wireless DataTrace or SenseAnywhere dataloggers or should you rent a Kaye Validator with thermocouples, RH or CO2 sensors?

  • If you have experience with one of these datalogging systems, order the type you are familiar with if it meets application requirements.
  • Masy rental equipment comes with a FAQ/Quick Reference Guide, and our knowledgeable support team can answer specific application questions.
  • Datatrace wireless datalogging systems (MPIII, MPRF) are typically used for reach in and walk in chambers, with a range of -70°C to 150°C.
  • SenseAnywhere wireless datalogging systems can be used for all temperature chambers, with a range of -196°C to 150°C and some RH applications.
  • Kaye Validator datalogging systems must be wired with thermocouples, RH or CO2 sensors, specific to your application, and can be used for validation all chambers, with temperature, RH or CO2 application.

What sensors should you rent for chamber mapping projects?

  • Rent wireless temperature dataloggers or a Kaye Validator datalogger with purchased ultra-premium validation thermocouples when mapping reach-in refrigerators and freezers. A one-time thermocouple purchase can be used for multiple projects. 
  • For stability chambers and incubators, use wireless temperature, RH or CO2 sensors, or a Kaye Validation datalogger with thermocouples, RH or CO2 sensors (which have been specifically configured and wired to the SIM).
  • For warehouses or large rooms, wireless systems that display live data is a time saver.  Wireless sensors are easier to place instead of long thermocouples, which can be caught or damaged in an active warehouse. See chart below as a general reference.

Do you need to rent a temperature bath and temperature standard?

  • You can rent temperature baths and a temperature standard to perform sensor pre- and post-calibration processes if you are familiar with the calibration equipment and the high and low calibration criteria. 
  • Temperature baths have a specific range of use, for instance, a Kaye HTR-400 is used for hot applications above 30°C such as incubators, ovens, sterilizers, depyrogenation ovens. An LTR (low temperature range) model cannot be used for those applications as it is inaccurate at higher temperatures.
  • You can order sensors pre- and post-calibrated for convenience and time savings. Identify the applications you will be mapping, such as refrigerators, freezers, incubators, sterilizers, ovens or warehouses, etc.  Whether you are choosing wireless dataloggers or Kaye Validation dataloggers, they will be calibrated at the range and at the point of use. Additionally, when renting a Kaye Validation datalogger, it can be wired with thermocouples and additional sensors such as RH or CO2 that will also be appropriate for your use.

Ancillary Items

Ask your Masy Rental Specialist which accessories will make your project easier and successful.

  • Laptop with datalogger system software installed
  • Magnetic holders for wireless sensors
  • Folding wheeled validation carts
  • Rubber Fab gaskets and clamps for SIP applications
  • Thermocouple feedthrough

What items have a longer lead time?

  • Seasonal projects, such as summer and winter warehouse mapping projects, creates a small window for equipment needs such as wireless sensors. Order early to meet your project deadlines.  Summer warehouse mapping must start and end within summer dates (June 21 to September 20). Winter warehouse mapping must start and end with winter dates (December 21 to March 20).

All validation equipment for rent or purchase from Masy is calibrated and maintained according to documented procedures and schedules. Most equipment can be shipped within one business day, so you can begin your projects quickly. Plan ahead and place your order to meet your project deadlines.

Masy also provides GMP biostorage, NVLAP Accredited calibrations, GMP/GAMP5 compliant temperature monitoring systems and on-site IQ/OQ/PQ validation services. To learn more about chamber mapping, read our recent article on sensor placement best practices.
