The 670SQ is the latest thermometer within the Isotech Primary SPRT 670 family. The design of this instrument is specially for optimum performance up to the aluminium tip. Its construction allows the four internal platinum electrode wires to expand and contract. This is the same way as silver-tip thermometers. The entire quartz construction of the supporting elements gives the most stable performance with minimal drift, and a unique platinum steel shield prevents heat build-up on the inside of the casing.
Due to the temperature range and design of this new device we can now offer 25.5 Ohm (Ro) and 100 Ohm (Ro). The construction, including the spiral sensor element, heat-shunt baffles and light scattering barriers, provides a thermometer with unsurpassed stability.
The 670SQ goes beyond the temperature range of the oxide growth to the level at which the oxide separates. The filling of the 670 consists of a unique argon/oxygen mixture. A 2.5 meter long, low thermal EMF, high temperature, shielded cable is connected in the handle. This is done via a voltage reducing transition in the fully pure platinum construction of the thermometer.
Gold-plated U-shaped clamps complete the cable construction and the 670SQ are also present in the elegant, softly padded case. The 670SQ will be shipped after the stabilization process is complete. This is when the reproducibility of RTPW is within 0.0005°C after peaks to the extremes of its temperature range. The values of RTPW and Wga are standard.
The 670SQ can only be certified with RTPW and Wga or with full UKAS calibration. You will receive an internationally Fixed Point calibration certificate. For best accuracy, the recommended maximum measurement currents are 1mA for 25.5Ω (Ro) and 0.5mA for 100Ω (Ro).
The 670SQ 650mm long is our recommended SPRT and offers ultra stability, with superior vibration, shock, immersion and automatic heating characteristics. From the success of the original Model 670 SPRTs, Isotech has introduced new models in the 670 series with a metal casing and low temperature models.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
