Top 10 FAQs about Masy Rental Equipment

Our Equipment Rental and Sales Manager, Steven Kenney, leverages his years of experience solving challenges for customers and recently compiled a list of the most frequently asked questions about our services.

Q: What equipment does Masy have available for rent?

A: Masy is recognized for the largest fleet of qualification, validation, calibration, and metrology equipment in North America. This includes all equipment needed for warehouse monitoring, thermal mapping, and validating a wide range of chambers, including autoclaves, incubators, ultra-low freezers, refrigerators, lyophilizers, depyrogenation ovens, warehouses and more. More specifically we rent Kaye AVS and V2K validators, dry block calibrators (dry baths) from Kaye and Fluke, IRTDs, feed through devices, DataTrace wireless dataloggers from Mesa as well as the SenseAnywhere wireless monitoring solution. All equipment is available for rent or for sale. Masy also offers a large selection of popular lengths for Type T FEP and Kapton thermocouples

Q: Do you sell the same equipment that you rent?

A: Yes, virtually all our rental equipment can be purchased new. This gives you a unique “try before you buy” advantage. All equipment is verified, inspected, and calibrated to the highest standards in our state-of-the-art calibration lab, complete with SI-traceable calibration certificate.

Q: How long can I rent equipment for?

A: The minimal rental period is one month with unlimited duration for as long as you need the equipment. If you find that you need equipment longer than originally anticipated, we can revisit your agreement for an extension.

Q: Can I rent equipment for projects where 21 CFR Part 11 compliance is required?

A: Yes. We frequently rent equipment for projects where 21 CFR Part 11 compliance is required. All calibrated rental equipment comes with proper calibration certificates. If you rent multiple wireless dataloggers, you can expect each logger to arrive with a dedicated calibration documentation.

Q: Why should I rent wireless dataloggers?

A: Customers often rely on the proven combination of Kaye validators and thermocouples for mapping various conditions. However, wireless dataloggers offer an equally dependable option with greater convenience. Wireless dataloggers accurately obtain data for pressure, humidity, CO2 and temp. And in contrast, they are easier to deploy, transport, and ship while offering increased installation flexibility. These loggers can be used simultaneously to verify more equipment than a wired system. For example, the Mesa DataTrace system can support hundreds of sensors deployed at the same time, while only requiring one laptop and one programming interface. SenseAnywhere can handle numerous loggers with a remarkable 10-year battery life and 2-month onboard memory at 5-minute sampling rate that features anytime cloud-based reporting.

Q: Do wireless dataloggers need to be calibrated?

A: Yes. Measurement accuracy is dependent on properly calibrated wireless dataloggers. Proof of calibration is often required, such as in applications where 21 CFR Part 11 requirements exist.

Q: Can I rent thermocouples?

A: No, here’s why. Thermocouples are comprised of wire and are susceptible to damage. To ensure consistent quality and uncompromised measurements, we only sell thermocouples. Masy maintains a very large inventory of Type T FEP and Kapton thermocouples that can be used in a wide range of environments and at temperatures from -200 oC to +350 oC.

Q: How do you calibrate thermocouples?

A: With the lowest uncertainties. To ensure accuracy, thermocouples (TCs) must be calibrated before use in any application. This process requires a combination of various equipment. Primarily a Kaye AVS or V2K validator, a dry-well calibrator (or bath), and a temperature standard—such as an IRTD—are used together for SI-traceable calibration.

Q: Can I make my own Type-T thermocouples?

A: Maybe. Masy sells FEP and Kapton thermocouples wire in bulk spools of up to 1,000 feet. If you have the right equipment, you can make your own thermocouples. However, we encourage customers to consider the risks and complexities. To make a thermocouple you must weld the conductors at one end of the wire together to form a quality circuit. The only way to do this successfully (without contaminating the connections) is by welding the tip in a contaminant-free environment. Masy has special equipment to perform the weld in an envelope of argon gas. Any other method of connecting the conductors, such as soldering or just twisting the ends together will dramatically impact the performance of the thermocouple and yield unreliable results. If you are validating a chamber, it is highly recommended to use pre-made thermocouples with a solid reputation of accuracy and reliability. Customers have depended on Masy for thermocouples for more than 35 years and we continuously stock thermocouples at various lengths from 15 feet to 50 feet.

Q: Should I rent a Kaye AVS or a Kaye Validator 2000?

A: Kaye is a very respected manufacturer and both pieces of equipment are renowned throughout the industry. However, there are significant differences that will influence your decision. The Validator 2000 (or V2K as it’s commonly called), can accommodate three sensor input modules (SIMs) on the back of the unit. Each SIM can accommodate 12 sensors, allowing the V2K to accept a total of 36 sensors. The AVS (Advanced Validation System) can accommodate four SIMs yielding up to a total of 48 sensors. The AVS (model X2017) is the newest model and is fully supported by Kaye. The Kaye AVS uses a wireless console supporting Microsoft Windows 10 while its predecessor, the V2K, requires a separate standalone laptop to operate. Please note that the SIMs are not interchangeable between units. Also, the V2K has been discontinued from Kaye and uses should expect limited support. Our Kaye equipment page can be found here.
