Dobbie Bros' used to market thermometers, but they were bought out some time ago. Wika are the distributors now. Just goggle "side entry thermometer". Dial type thermos are stilll used extensively in industry. You may pay a bit more for them but they are generally quite robust, weatherproof, usually 316 SS, field calibratable, and user adjustable for zero error, and more importantly, accurate.
