• Electronic temperature and humidity sensing with LCD display.
• Optional extension cables for remote sensor placement.
• Battery operation or a suitable external DC supply.
• Desktop or wall-mounted installation.

Being phased out: confirm availability before ordering. Alternatives include the Sato Sigma II for paper records, Sato SK-L754 for electronic logging and Vaisala viewLinc for centralised monitoring.

The Sekonic ST-50M digital thermohygrograph is discontinued. It combined temperature and humidity measurement with paper chart recording and SD-card storage.

• Paper records: consider the Sato Sigma II NSII-Q.
• Electronic records: consider the Sato SK-L754 temperature and humidity data logger.
• Centralised monitoring and alarms: consider Vaisala RFL100, AP10 and viewLinc.

Contact Seacom to match the replacement to your recording requirements. Features and accessories differ from the original ST-50M.
