The PT100-5 is a compact and versatile probe-type Platinum Resistance Thermometer (PT100 RTD) featuring a stainless steel sensing tube without screw fittings. This design makes it an ideal choice for applications where the sensor is inserted directly into a thermowell, clamped in place, or embedded within equipment — offering a clean, low-profile installation without the need for threaded process connections.

The PT100-5 is fully waterproof, making it well suited for wet or humid environments. Lead wire material and length are fully customisable, and the sensor is available in three probe diameters and multiple probe lengths to accommodate a wide range of installation geometries. Its straightforward construction and broad compatibility make it a popular choice for both OEM integration and field replacement applications.

This is a single phase SCR power regulators and temperature controllers 2 in 1 units, in a typical heating system, you would need a temperature controller and a SCR power regulators, and they are two separate devices, we go further and build this two devices in one package, this saves a lot of efforts for panel builders when it comes down to wiring, and RS-485 modbus is a standard feature, controller can be integrated to systems with HMI or PLC etc. the load can be directed wired to this thyristor power regulators, and it works with all kinds of inputs, Thermocuple, RTD, analog signal

The PT100-8 is a probe-type Platinum Resistance Thermometer (PT100 RTD) distinguished by its adjustable insertion depth — a key feature that sets it apart from fixed-length sensors. A stainless steel compression fitting is integrated into the assembly, forming a liquid-tight or pressure-tight seal against the process wall while allowing the operator to slide and lock the probe at any desired insertion depth before or after installation. This eliminates the need to specify a fixed immersion length at the time of ordering and greatly simplifies retrofitting into existing equipment.

The probe is constructed from 304 stainless steel and is available in diameters of 4 mm, 5 mm, and 6 mm. The lead cable is shielded with a metal braid and covered with PTFE insulation, delivering low noise, high mechanical strength, and excellent resistance to elevated temperatures. The PT100-8 is compatible with a wide range of process fittings — including NPT, BSP, and metric threads — and is available in a waterproof configuration, making it suitable for measuring the temperature of both air and liquids across diverse industrial environments.

This thermal controller offers some basic features with limited configuration options, it is for much less demanding application, despite it's cost-effective nature, still it offers Relay, SSR Drive and analog output, analog output being at the same price with the relay and SSR Drive output, maximum 2 alarms and heating+cooling control at the same time are possible, the alarm output can be used as a sub output to control a fan or valve in a system, TC/RTD and analog inputs compatible, 24VDC source and 85~265Vac source optional

The PT100-9 is a tri-clamp liquid-tight Platinum Resistance Thermometer (PT100 RTD) engineered for reliable and accurate temperature measurement in sanitary and process environments where a secure, leak-proof connection is essential. The sensor features a stainless steel flanged tri-clamp fitting that forms a robust liquid-tight seal, making it ideally suited for food processing, dairy, brewing, pharmaceutical, and chemical applications where hygiene and contamination prevention are paramount.

The probe is constructed from stainless steel and is available in three diameters (4 mm, 5 mm, and 6 mm) with probe lengths of 30 mm, 40 mm, or 50 mm, all of which can be customised to meet specific installation requirements. Lead wire material is fully selectable — stainless steel braid, silicone, fiberglass, or Teflon — allowing the sensor to be matched to the thermal and chemical conditions of the surrounding environment. Lead wire length is available in 2 m, 3 m, or 5 m. The “-TC” suffix in the ordering code designates the tri-clamp liquid-tight connection, clearly distinguishing this series from standard probe-type RTDs.

The PT100-12 is a PT100 Platinum Resistance Thermometer featuring an adjustable compression fitting combined with a robust Form B aluminium connection box (connection head). This combination delivers two key advantages in a single assembly: the compression fitting allows the probe insertion depth to be set and locked at any position within the fitting stroke, eliminating the need for custom-length probes during installation; and the sealed connection box provides a weather-resistant, vibration-tolerant housing for field wiring that is well suited to demanding industrial environments.

The sensor complies with EN 60751 and covers a temperature range of −70 °C to +300 °C, making it suitable for a wide spectrum of process and industrial applications. The stainless steel probe is available in three diameters — 4 mm, 5 mm, and 6 mm — and three standard lengths of 50 mm, 100 mm, and 150 mm, all of which can be customised to order. Adjustable process fittings are available in ½ NPT, ¼ NPT, and ¼ BSP thread forms, enabling direct installation into standard process pipework and vessels without adapters. The connection box accepts standard conduit entries, and the sensor ships without lead wire, with all field connections made inside the terminal block housed within the connection box.

CH102, CH402, CH702, CH902 is a very popular controller on the markets, comes with relay and SSR Drive output, relay and SSR Drive output at the same time, faciliated wiht different terminals, if you want to use the relay output, then connect your AC contractor or SSR with the relay output terminal, if you want to use SSR drive output, then connect your solid state relay with SSR Drive output terminal, with 1 alarm and works on wide range of power supply, works with thermocuple and RTD inputs despite the cost being very competetive.

The PT100-14 is a bolt-on PT100 Platinum Resistance Thermometer designed for direct surface temperature measurement. The sensor element is integrated into a ring (eye) terminal lug that is bolted or screwed directly onto the surface to be measured — such as a motor casing, heat sink, pipe outer wall, bearing housing, or structural component — ensuring intimate thermal contact without the need for a thermowell, probe pocket, or adhesive. This makes the PT100-14 an exceptionally convenient and cost-effective solution wherever surface temperature monitoring is required.

The ring terminal inner diameter is available in 6 mm or 8 mm as standard, and can be customised to match any bolt or screw size specified by the customer. The sensor is supplied with a stainless steel braided cable for mechanical protection and EMI shielding, and the lead wire material is fully selectable from stainless steel braid, silicone, fiberglass, or Teflon to suit the thermal and chemical conditions of the installation environment. Standard cable lengths are 2 m, 3 m, and 5 m, with custom lengths available on request. The sensor is available in temperature ranges up to 100 °C, 200 °C, or 300 °C.
